By using dynamic programming on a tree decomposition or branch-decomposition of a planar graph, many NP-hard optimization problems may be solved in time exponential in √n or √n log n. For instance, bounds of this form are known for finding maximum independent sets, Steiner trees, and Hamiltonian cycles, and for solving the travelling salesman problem on planar graphs.; ; ; . Similar methods involving separator theorems for geometric graphs may be used to solve Euclidean travelling salesman problem and Steiner tree construction problems in time bounds of the same form.. For parameterized problems that admit a kernelization that preserves planarity and reduces the input graph to a kernel of size linear in the input parameter, this approach can be used to design fixed-parameter tractable algorithms the running time of which depends polynomially on the size of the input graph and exponentially on √k, where k is the parameter of the algorithm.

However, it is unlikely that such a subexponential time bound is possible for the clique problem in arbitrary graphs, as it would imply similarly subexponential bounds for many other standard NP-complete problems.
Clarke has pursued business interests since 1993, through being a travelling salesman for MTS Nationwide, a firm based at Wakefield, West Yorkshire. He has, however, remained an outspoken critic of the game, and like all the Leeds United players of the Revie era, has remained fiercely protective of the reputation of both the manager and the club. He has suffered from arthritic knees in recent years. Clarke now lives in Scunthorpe, Lincolnshire.

Jillian Beardwood (1934–2019) was a British mathematician known for the Beardwood-Halton-Hammersley Theorem. Published by the Cambridge Philosophical Society in a 1959 article entitled "The Shortest Path Through Many Points", the theorem provides a practical solution to the "travelling salesman problem". The authors derived an asymptotic formula to determine the length of the shortest route for a salesman who starts at a home or office and visits a fixed number of locations before returning to the start.
The problem of determining the shortest closed path through a given set of n points is often called the “travelling salesman problem.” A salesman, starting at and finally returning to his base, visits (n-1) other towns by the shortest possible route. If it is large, it may be prohibitively difficult to calculate the total mileages for each of the (n-1)! orders in which the towns may be visited, and to choose the smallest total.
In adult discourse the phrase "connect the dots" can be used as a metaphor to illustrate an ability (or inability) to associate one idea with another, to find the "big picture", or salient feature, in a mass of data. Reuven Feuerstein features the connection of dots as the first tool in his cognitive development program. The travelling salesman problem asks what numbers to assign to a set of points to minimize the length of the drawing.
He became very active in his church, keeping himself busy to avoid examining his homosexual feelings. McArthur left his job at Eaton's in 1978 and began working as a travelling salesman for McGregor Socks. He worked by himself, travelling from town to town, soliciting department stores to carry his merchandise. He worked territories including Northern Ontario and the Greater Toronto Area (GTA), and as he gained more territories he employed "counters" to stock, prepare, and reorder merchandise.
The Man Who Knew Coolidge is a 1928 satirical novel by Sinclair Lewis. It features the return of several characters from Lewis' previous works, including George Babbitt and Elmer Gantry. Additionally, it sees a return to the familiar territory of Lewis' fictional American city of Zenith, in the state of Winnemac. Presented as six long, uninterrupted monologues by Lowell Schmalz, a travelling salesman in office supplies, the eponymous first section was originally published in The American Mercury in 1927.
Carter was born in Crafton, Texas. After his mother died in 1892, he moved away from his remaining family, to Bowie, Texas, where he supported himself with a variety of odd jobs. At those jobs, he learned salesmanship, and became a travelling salesman as a young man. Bowie residents have recalled that he was one of the original "chicken & bread boys" who sold sandwiches represented as "chicken" to passengers at the rail station during the depression.
In some genetic algorithms, not all possible chromosomes represent valid solutions. In some cases, it is possible to use specialized crossover and mutation operators that are designed to avoid violating the constraints of the problem. For example, a genetic algorithm solving the travelling salesman problem may use an ordered list of cities to represent a solution path. Such a chromosome only represents a valid solution if the list contains all the cities that the salesman must visit.
A more realistic problem we might wish to solve is the travelling salesman problem. In this problem, we seek an ordered list of cities that results in the shortest trip for the salesman to travel. Suppose there are six cities, which we'll call A, B, C, D, E, and F. A good design for our chromosome might be the ordered list we want to try. An example chromosome we might encounter in the population might be `DFABEC`.
After World War I, Temple was treated as a war hero by his employer.Melnyk, p. 174 The Arrow Shirt Company president met Temple's train in Montreal, where he promoted him to travelling salesman for the company's Winnipeg office.

Dixon had originally retired from cricket at the end of the 1957 season to become a travelling salesman before reconsidering at the start of the 1958 season and rejoining the county. After retirement he coached cricket at Tonbridge School. He coached, among others, Kent and England swing bowler Richard Ellison who credited Dixon with developing his talent. Ellison was selected as one of Wisden's four Cricketers of the Year in 1986.The Wisden Collector's Guide pp.250-251.
In the general case, finding a shortest travelling salesman tour is NPO-complete. If the distance measure is a metric (and thus symmetric), the problem becomes APX-complete and the algorithm of Christofides and Serdyukov approximates it within 1.5. A 2020 preprint improves this bound to 1.5-10-36. The best known inapproximability bound is 123/122. If the distances are restricted to 1 and 2 (but still are a metric) the approximation ratio becomes 8/7.
Dörnigheim's existence was first documented in the year 793. According to a document Wolfbodo donated the Maingau including "Turinchheim" (old name of the city) to the Abbot of Lorsch. The proprietorship was shared between the counts of Hanau and the bishops of Mainz. Ferry at Dörnigheim Because of its well situated location between Hanau in the east and Frankfurt am Main in the west Dörnigheim was favoured as a last stop for travelling salesman on their way to Frankfurt.

He lived in Massachusetts for a few years where two of his children were born.
In optimization, 3-opt is a simple local search algorithm for solving the travelling salesman problem and related network optimization problems. 3-opt analysis involves deleting 3 connections (or edges) in a network (or tour), to create 3 sub-tours. Then the 7 different ways of reconnecting the network are analysed to find the optimum one. This process is then repeated for a different set of 3 connections, until all possible combinations have been tried in a network.
Several researchers have studied the complexity of exponential time algorithms restricted to cubic graphs. For instance, by applying dynamic programming to a path decomposition of the graph, Fomin and Høie showed how to find their maximum independent sets in time 2n/6 + o(n). The travelling salesman problem in cubic graphs can be solved in time O(1.2312n) and polynomial space... Several important graph optimization problems are APX hard, meaning that, although they have approximation algorithms whose approximation ratio is bounded by a constant, they do not have polynomial time approximation schemes whose approximation ratio tends to 1 unless P=NP. These include the problems of finding a minimum vertex cover, maximum independent set, minimum dominating set, and maximum cut.. The crossing number (the minimum number of edges which cross in any graph drawing) of a cubic graph is also NP-hard for cubic graphs but may be approximated.. The Travelling Salesman Problem on cubic graphs has been proven to be NP-hard to approximate to within any factor less than 1153/1152..

In 1974, Jennifer moved in with her aunt, Christine Barford, after separating from Roger after he became a travelling salesman. Fresh from the divorce to her first husband, Roger Travers-Macy, Jennifer met the Sherborne-educated Brian Aldridge at a dinner party hosted by Carol Tregorran. Not long after, the couple wed on 29 May 1976 . The official Archers website says this began "Jennifer's ascendance to the social pinnacle of Ambridge" and developed the character into "the elegant, capable pillar of the community".
Thus, the efficiency of the process may be increased by many orders of magnitude. Moreover, the inversion operator has the opportunity to place steps in consecutive order or any other suitable order in favour of survival or efficiency.See for instance Evolution-in-a- nutshell or example in travelling salesman problem, in particular the use of an edge recombination operator. A variation, where the population as a whole is evolved rather than its individual members, is known as gene pool recombination.

They agreed not to work together, but this changed in 1972 when she appeared in the Rodney Bewes sitcom Albert!, which Hitchcock co-directed, and again later in the same year, when she acted in Turnbull's Finest Half-Hour, a comedy series starring Michael Bates and produced by Hitchcock.
Jef Vandemeulebroek was the son of Franciscus-Xaverius Vandemeulebroek, a travelling salesman, and Anna Maria Ludovica Bosmans. After receiving a degree in Medicine from the Free University of Brussels in 1901, he set up a practice in Laeken. On his death- bed in October 1958, he married his long-term companion Louisa Degueldre (1898–1985), with whom he had had a son, Jacques, who had been born in Ixelles in 1932. Throughout his life, he encountered repeated problems with the accepted spelling of his name.
The main part of the film shows the train travelling through the New South Wales countryside through disparate locations including the Sydney suburbs, Hawkesbury River Railway Bridge, Ten Tunnels Deviation, Blayney station and the Picton-Mittagong loop line. These scenes are interspersed with vignettes of life the 1940s including a travelling salesman, a country wedding and soldiers in a pub, all linked to the train journey. Most of the audio is live sound of the train, with some overlaid with original music by George Dreyfus.
The plots are typically neat puzzles with less personal content than the Wimsey stories, although Egg himself emerges as a memorable and likeable character. A novel would probably not have fitted the nature of the Egg stories. By occupation, Egg is a travelling salesman for an importer and distributor of fine wines and spirits (Wimsey is a well-known connoisseur of the same). His knowledge of all aspects of the vintner's trade is useful in determining the exact circumstances of several cases of poisoning.
Beech was a supporter of the IWW, and attended the 2nd World Congress of the Comintern as a supporter of it. This convinced him to join the Communist Party (British Section of the Third International), and he was one of its two delegates in the unity negotiations which re-established the Communist Party of Great Britain (CPGB). He served on its executive for most of 1921, while working as a travelling salesman. During the mid-1920s, Beech devoted much of his time to the National Minority Movement.
In 1899, Votruba had this commercial building constructed to house a general store selling groceries, harnesses, and notions. By 1903, Vortuba had given up the business in favor of becoming a travelling salesman, and a new business, the East Jordan Harness Company, occupied the building. This was replaced by a furniture store, possibly owned by Votruba, in 1905. In 1907, James Votruba was back in the general store business, and opened a new store selling groceries, harness, farm implements, confectionery, and other goods in the Votruba block.
In the Land of Oz, the Ozians are rejoicing over the demise of Elphaba, the Wicked Witch of the West. Glinda the Good Witch floats in and discusses Elphaba's past, wherein Elphaba's mother had an affair with a travelling salesman, after Elphaba's father, who just happened to be the governor of Munchkinland, went out of town. She becomes pregnant and gives birth to a baby girl with green skin ("No One Mourns the Wicked"). One of the Ozians asks Glinda if she and Elphaba were friends.
In the winter term of 1875-76, he attended the Henry Military School in Henry, Illinois. He then worked as a travelling salesman for a firm in Clyde, Ohio until 1880. In 1880, Thomas Jefferson Butcher announced that he was leaving his secure job with the railroad and moving west, to establish a homestead in Custer County, Nebraska. Although Solomon Butcher had a good job, he had grown tired of his work, and "had already thought seriously of seeking my fortune in the great west".
Little was born on 19 July 1895 at Hawthorn, a suburb of Melbourne, to Canadian James Little, a seller of medical and surgical books, and his Victorian-born wife Susan. His family heritage was Scottish, and he was educated at Camberwell Grammar School and Scotch College, Melbourne,Rosel, Unknown Warrior, pp. 14–19 where he was a swimming medallist. He entered his father's business as a travelling salesman, and was living with his family at Windsor when World War I broke out in August 1914.
In numerical analysis, hill climbing is a mathematical optimization technique which belongs to the family of local search. It is an iterative algorithm that starts with an arbitrary solution to a problem, then attempts to find a better solution by making an incremental change to the solution. If the change produces a better solution, another incremental change is made to the new solution, and so on until no further improvements can be found. For example, hill climbing can be applied to the travelling salesman problem.
Shen Lin and Brian Kernighan first published their method in 1972, and it was the most reliable heuristic for solving travelling salesman problems for nearly two decades. More advanced variable- opt methods were developed at Bell Labs in the late 1980s by David Johnson and his research team. These methods (sometimes called Lin–Kernighan–Johnson) build on the Lin–Kernighan method, adding ideas from tabu search and evolutionary computing. The basic Lin–Kernighan technique gives results that are guaranteed to be at least 3-opt.
Miller noted that although he wrote the play in 1947 and 1948, the play grew out of his life experiences, that included his father losing everything in the 1929 stock market crash. Miller claims that the role was actually modeled on one of his uncles. Dustin Hoffman says that the play was the first one he ever read and predated his interest in becoming an actor. He noted that the play resonated with him because his father was a travelling salesman and he had an older brother.
Mitchell has been an NSF Presidential Young Investigator, Fulbright Scholar, and a recipient of the President's Award for Excellence in Scholarship and Creative Activities. He shared the 2010 Gödel Prize with Sanjeev Arora for devising a polynomial-time approximation scheme for the Euclidean travelling salesman problem... In 2011 the Association for Computing Machinery listed him as an ACM Fellow for his research in computational geometry and approximation algorithms.ACM Names Fellows for Computing Advances that Are Driving Innovation , Association for Computing Machinery, December 8, 2011. He has also won numerous teaching awards.
In a quiet English town, schoolgirl Betty Kane (Ann Stephens) claims that the owners of an isolated house ("The Franchise") , spinster Marion Sharpe (Dulcie Gray) and Marion's mother (Marjorie Fielding), kidnapped and beat her. The police believe Betty's story, but local lawyer Robert Blair (Michael Denison), a bachelor, is sceptical. Risking ostracism from the community, Blair quietly sets about proving the innocence of the two women. It emerges that the 14 year old girl was actually claiming to be 19 and was having an affair with a travelling salesman.
Felt's sister wife Elizabeth Mineer went into hiding, and Felt often arranged for Elizabeth to visit her children for a day, driving a disguised Elizabeth to their home in a cart in the middle of the night. Louie Felt Keysor, one of the daughters of Elizabeth Mineer, died, and Felt helped raise her four children. Joseph Felt served a mission in 1883 in the Indian Territories and again 1885–1887 in the Eastern States. After his return, he still traveled frequently in his work as a travelling salesman for ZCMI.
Hester Bevins is tired of life in the small town where she has lived all her life. Although she has a boyfriend, Gerald Smith, who is in love with her, she deserts him and takes a train to New York with a travelling salesman. Bevins meets a rich older man, Charles Wheeler, who provides her with all the luxuries she wants in return for being his girlfriend. One day, Bevins' friends invite her on a motor trip to Hot Springs, which is about thirty miles from her old home town, which she decides to visit.
Clarkson was born in Doncaster, West Riding of Yorkshire, the son of Shirley Gabrielle Clarkson (1934–2014), a teacher, and Edward Grenville Clarkson (1932–1994), a travelling salesman. His parents, who ran a business selling tea cosies, put their son's name down in advance for private schools, with no idea how they were going to pay the fees. However, shortly before his admission, when he was 13, his parents made two Paddington Bear stuffed toys for Clarkson and his sister Joanna. These proved so popular that they started selling them through the business.
As described in a film magazine, Sid Chambers (Peters), a thief, is released from prison and rejoins his pals at a Greek restaurant. He finds his former second story man Bob Drake (Ainsworth), without funds as he has developed a cough that discloses his whereabouts. The two crooks go to the country where Sid falls in love with a young woman, Laura Chadwick (Rich), who wants him to go straight. He becomes a travelling salesman and they live quietly in a small cottage until detective Mark Shadwell (Jennings) shows up.
The Cadiner Saal at Kempinski's, Berlin Interior of Weinhaus Kempinski Kempinski was born in Raschkow, Province of Posen, Kingdom of Prussia (Raszków, Poland), he became a travelling salesman in winetrade in his homeregion. Kempinski and his younger brother operated a wine tavern at the Ring (Market Square) of Breslau (Wrocław). In 1872 he moved to Berlin and started a small premise at Kronenstraße and soon after the M. Kempinski & Co. wine restaurant at Friedrichstraße / Leipziger Straße junction. The restaurant became popular for its huge selection of wine and seasonal delicacies like oysters and crayfish.
This led to the police watching their house, but her husband's job as a travelling salesman provided ample cover for their activities. The Irish Republican Brotherhood member, Bulmer Hobson, who opposed the Easter Rising was detained at the O'Doherty home until the Rising had begun. Her husband had been tasked by Tom Clarke in rebuilding the IRB after the Rising, with the temporary supreme council meeting at their home at 32 Connaught Street, Phibsborough. From 1916 to 1917, O'Doherty worked full- time as the voluntary secretary and trustee of the National Aid Society Office.
In Singapore, the French proconsul introduces him to a small boy who is actually a venerable doctor and the sailor adopts the boy as his son. The sailor then witnesses his ship sink, only to miraculously resurface. He finds a replacement mother who is a stowaway on board and then two criminal brothers in Tangier. When he returns to Valparaíso, he finds his actual mother and sister have disappeared, encounters an eccentric Portuguese travelling salesman, and then falls in lust with the mambo dancer Matilde, a femme fatale whose mouth is her only orifice.
More details of Cook's work with Concorde, suitable for more serious researchers on the problem and on related topics, can be found in an earlier book by Cook with David Applegate, Robert E. Bixby and Václav Chvátal, The Traveling Salesman Problem: A Computational Study (2007). Other books on the travelling salesman problem, also more technical than In Pursuit of the Traveling Salesman, include The Traveling Salesman Problem: A Guided Tour of Combinatorial Optimization (by Lawler, Lenstra, Rinnooy Kan, and Shmoys, 1985) and The Traveling Salesman Problem and Its Variations (by Gutin and Punnen, 2006).
The first use of the farthest-first traversal was by in connection with heuristics for the travelling salesman problem. In the farthest-insertion heuristic, discussed by Rosenkrantz et al., a tour is built up incrementally, by adding one point at a time in the ordering given by a farthest-first traversal. To add each point to the traveling salesman tour of the previous points, this heuristic considers all possible ways of breaking one edge of the tour and replacing it by two edges through the new point, and chooses the cheapest of these replacements.
These findings were able to explain the lack of progress that had been seen in the research community on the approximability of a number of optimization problems, including 3SAT, the Independent Set problem, and the Travelling Salesman Problem.Christos Papadimitriou , Mihalis Yannakakis, Optimization, approximation, and complexity classes, Proceedings of the twentieth annual ACM symposium on Theory of computing, p.229-234, 2–4 May 1988. Yannakakis and Carsten Lund presented a number of findings regarding the hardness of computing approximations at the Annual ACM Symposium on Theory of Computing of 1993.
Born in 1912, Kersh began to write at the age of eight. After leaving school, he worked as, amongst other things, a cinema manager, bodyguard, debt collector, fish and chip cook, travelling salesman, French teacher and all-in wrestler whilst attempting to succeed as a writer. Kersh's first novel, Jews Without Jehovah, an autobiographical tale of growing up poor and Jewish, was published in 1934. Kersh, however, had not sufficiently concealed the identities of some of the characters, and a member of his family sued for libel; as a result, the book was quickly withdrawn.
Taitz was born to Izhok-Aaron (Isaac- Arkady) Z. Taitz () (1868–1935), a travelling salesman who was born in Kaunas,Lithuania, Russian Empire,, and Sara (Sophia) M. Vilenchuk () (1874–1951), who was born in a suburb of Kaunas. In 1925 Taitz married Iraida B. Zeest () (1902–1981), who was born in Saint Petersburg. She studied at Moscow State University and graduated from the Faculty of Philology, with a Doctor of Science in History degree. She worked for the Pushkin State Museum of Fine Arts and later for the Institute of Archaeology, USSR Academy of Sciences.
Following the war, he went back to the Trading Company before joining A.E. Hickman & Co. as a travelling salesman. From 1928 to 1932, Quinton was manager for an export division of the Monroe Export Co. He married Ella Blackmore. Quinton was elected to the Newfoundland House of Assembly in 1928 representing Bonavista and was re-elected in 1932 defeating a young Joey Smallwood. He served as minister of public works in the Newfoundland government until responsible government was suspended in 1934 in favour of a Commission of Government appointed by London.
Gordon Downie was born in Amherstview, Ontario, and raised in Kingston, Ontario, along with his brothers Mike and Patrick, and sisters Charlyn and Paula. He was the son of Lorna (Neal) and Edgar Charles Downie, a travelling salesman, later a real estate broker and developer. In Kingston, he befriended the musicians who would become The Tragically Hip, while attending the downtown Kingston high school Kingston Collegiate and Vocational Institute. He attended Queen's University where he majored in film studies, graduating with a Bachelor of Arts and Science in 1986.
History of the Staffordshire Potteries – Simeon Shaw Knight became sole proprietor of the business in 1853 but shortly afterwards took Henry Wileman as a partner, trading as Knight & Wileman. Three years later Knight retired and Henry Wileman continued the business in his own name. In 1862 Henry Wileman employed Joseph Shelley [link] (whose family had at one time produced pottery on the site now occupied by the Gladstone Museum[link]) as a travelling salesman. In 1864 Henry Wileman died and his two sons James F and Charles J took over the business.
Aitana Sánchez-Gijón de Angelis (born 5 November 1968 in Rome, Italy) is a Spanish film actress. She was born in Rome, to father Ángel Sánchez-Gijón Martínez, a history professor, and Italian mother, Fiorella de Angelis, a mathematics professor. She grew up in Spain. Best known for playing dramatic roles in Spain, Sánchez-Gijón first became known internationally for her portrayal of Victoria Aragon, a pregnant and abandoned Mexican-American winegrower's daughter who is helped by travelling salesman Paul Sutton (Keanu Reeves) in A Walk in the Clouds (1995).
12 (1918) After he was mustered out of the army, he worked in retail in Pittsburgh for a while, and later he worked in petroleum development in Pennsylvania for a year, boring twelve oil wells. He then became a travelling salesman of Rockingham style crockery throughout the Midwest. Homer then moved to New York where he worked with his brother Shakespeare Moore Laughlin as an importer of English earthenware. In 1873, they built a pottery in East Liverpool, Ohio, which they ran as Laughlin Brothers until 1879, when Homer bought out Shakespeare.
The first ACO algorithm was called the ant systemM. Dorigo, V. Maniezzo, et A. Colorni, Ant system: optimization by a colony of cooperating agents, IEEE Transactions on Systems, Man, and Cybernetics--Part B , volume 26, numéro 1, pages 29-41, 1996. and it was aimed to solve the travelling salesman problem, in which the goal is to find the shortest round-trip to link a series of cities. The general algorithm is relatively simple and based on a set of ants, each making one of the possible round-trips along the cities.
This proved to be his final fight. McCormick claimed that throughout his career he was never knocked out, and claimed damages in 1938 after an article in The People which was reproduced in the book Giants on Parade implied that he had been knocked out by Jimmy Wilde in their early sparring encounter before McCormick turned professional. He won the case and was awarded £1,050 damages. After retiring from boxing he found work as a travelling salesman and boxing instructor, also acting as a referee in several bouts.
Sturges was born in Chicago, Illinois, the son of Mary Estelle Dempsey (later known as Mary Desti or Mary D'Este) and travelling salesman Edmund C. Biden. His maternal grandparents, Catherine Campbell Smyth and Dominick d'Este Dempsey, were immigrants from Ireland, and his father was of English descent. When Sturges was three years old, his eccentric mother left America to pursue a singing career in Paris, where she annulled her marriage with Preston's father. Returning to America, Dempsey met her third husband, the wealthy stockbroker Solomon Sturges, who adopted Preston in 1902.
František R. Kraus was born in Josefov, then the Jewish quarter in Prague into a Jewish family of Robert Kraus, a travelling salesman and Matylda Kraus née Kollmann, a housewife. As it was common in better well-off Jewish families at that time, he obtained his basic education at a catholic Piarist convent school in Panská street. Later he continued at Realschule in Jindřišská street. He graduated at Classical High School in Kinský palace at the Old Town Square. He also attended the famous Talmud-Thora Schule in Josefov’s Jáchymova Street.
In 1994, his paper Molecular Computation of Solutions To Combinatorial Problems described the experimental use of DNA as a computational system. In it, he solved a seven-node instance of the Hamiltonian Graph problem, an NP- complete problem similar to the travelling salesman problem. While the solution to a seven-node instance is trivial, this paper is the first known instance of the successful use of DNA to compute an algorithm. DNA computing has been shown to have potential as a means to solve several other large-scale combinatorial search problems.
He plans to take Prindy to a secret location in the bush to continue the initiation process. As this is "men's business", the women are not permitted to be involved. Nell and Queeny do not want Prindy to be initiated into the tribe, as they want him to have the chance of a life in white society, and they track the men. In a violent confrontation, all three adults die, and Prindy wanders alone until he is rescued by an Indian travelling salesman, Ali Barbu, whose young daughter Savitra quickly falls for the boy.
The women steal his Fiat. Pee-wee then gets a car ride from a travelling salesman named Gordon, who visits a creepy snake farm with Pee-Wee in tow, and gives him a disguise kit. Pee-wee tries to hitch-hike, but nobody stops, so he seeks refuge at a farmhouse owned by Farmer Brown, who lets Pee- wee spend the night. Farmer Brown introduces Pee-wee to his nine daughters, each of whom have a romantic interest in Pee-wee and flirt with him all night long.
William "Willy" Loman is a fictional character and the protagonist of Arthur Miller's classic play Death of a Salesman, which debuted on Broadway with Lee J. Cobb playing Loman at the Morosco Theatre on February 10, 1949. Loman is a 63-year-old travelling salesman from Brooklyn with 34 years of experience with the same company who endures a pay cut and a firing during the play. He has difficulty dealing with his current state and has created a fantasy world to cope with his situation. This does not keep him from multiple suicide attempts.
When counterfeit $10 bills spread across the country, showing up at casinos and racetracks, the Treasury Department realizes that the bills are Deane's work. The officers set up surveillance on the counterfeit gang and find a travelling salesman who has been distributing the bills across the country, hoping to capture and interrogate him. However, a ruthless member of the counterfeiting gang (George Tobias) gets to the salesman first and kills him by throwing him out a window before he can talk and possibly lead the agents to the gang. The Secret Service then puts undercover agent John Riggs (Don DeFore) on the case.
In 1905 her widowed mother married Henry Walter Morris (1867–1934), a travelling salesman for a drapery company and in 1911 she was living with her mother and stepfather at Minard Road in Catford in London.1911 England Census for Margaret Sarah Whitefoot: London, Lewisham - Ancestry.com At about this time Morris met the Dutch revue artist Louis Davids at an intimate party for artistesBiografie van Louis Davids - Amsterdam Mokum TV and although her stepfather was against their relationship she moved to the Netherlands with him in 1913 with various sources claiming that she was fleeing from her stepfather's strict upbringing.
The scheduling of resources, usually subject to constraints, is the subject of several problems that are in the area of research known as operations research, usually in terms of finding an optimal solution or method for solving. For example, the nurse scheduling problem is concerned with scheduling a number of employees with typical constraints such as rotation of shifts, limits on overtime, etc. The travelling salesman problem is concerned with scheduling a series of journeys to minimize time or distance. Some of these problems may be solved efficiently with linear programming, but many scheduling problems require integer variables.
While the film follows stations and themes from the Odyssey, transferring them "to our country and our civilisation", a large part also consists of documentary shoots, showing places and landscapes in German- speaking Switzerland. Reisender Krieger was filmed without written dialogue, without artificial light, and using just a hand-held camera. According to Schocher, the manifest Dogma 95 where Danish directors made similar specifications, made him laugh: "Klopfenstein and me developed this earlier, we just didn't shout it out from the rooftops". The German title is ambiguous, as Reisender Krieger can be read as "Travelling salesman Krieger", but also as "Travelling Warrior".
Film still with Clarke and Arbuckle As described in a film publication, Bob Blake (Arbuckle), a travelling salesman, is the victim of a practical joke and gets off the train before his intended destination of Grand River. Bob is drenched in the pouring rain and, when he cannot find lodging, breaks into a private house that the sheriff is going to sell for a tax delinquency. The house belongs to Beth Elliott (Clarke), a telegraph operator at Grand River Station. Bob looks her up so he can pay for his lodging and falls in love with her.
A mysterious, middle-aged man wearing a dark suit and black leather gloves is the only customer in a Hoboken, New Jersey bar. He looks longingly at a picture of a woman that he keeps in his wallet. He then has a tense conversation with the bartender, in which he reveals that he once lived in Hoboken years ago, but is now passing through "on business" because he is a "travelling salesman." While the man is in the bar's restroom, a teenage boy named Lake, dressed as a cowboy and brandishing a gun, bursts into the bar.
The series begins as Karl (Nils Vogt), economist and accountant, is fired from his job and subsequently divorced by his greedy wife. After being helped out by his former colleague, Nils (Sven Nordin), and a travelling salesman, Henry (Arve Opsahl), the three become roommates as they make various attempts at making easy money or finding success. The first three series usually focused on single-episode stories, like most sitcoms, usually involving a plot to get rich in a hurry with disastrous results. It also had a large number of celebrity guest appearances, often closely related to the schemes attempted by the main characters.
Born in Stuttgart, the state capital of Baden-Württemberg, to Norbert Klopp, a travelling salesman and a former goalkeeper, Klopp grew up in the countryside in the Black Forest village of Glatten near Freudenstadt with two older sisters. He started playing for local club SV Glatten and later TuS Ergenzingen as a junior player, with the next stint at 1. FC Pforzheim and then at three Frankfurt clubs, Eintracht Frankfurt II, Viktoria Sindlingen and Rot-Weiss Frankfurt during his adolescence. Introduced to football through his father, Klopp was a supporter of VfB Stuttgart in his youth.
Gathering in the same room where they were celebrating in Act One we see how their lives have failed in different ways. Robin has become a dissolute travelling salesman, estranged from his wife Joan, Madge has failed to realise her socialist dreams, Carol is dead, Hazel is married to the sadistic but wealthy Ernest. Kay has succeeded to a certain extent as an independent woman but has not realised her dreams of novel writing. Worst of all, Mrs Conway's fortune has been squandered, the family home is to be sold and the children's inheritance is gone.
The multi-fragment (MF) algorithm is a heuristic or approximation algorithm for the travelling salesman problem (TSP) (and related problems). This algorithm is also sometimes called the "greedy algorithm" for the TSP. The algorithm builds a tour for the traveling salesman one edge at a time and thus maintains multiple tour fragments, each of which is a simple path in the complete graph of cities. At each stage, the algorithm selects the edge of minimal cost that either creates a new fragment, extends one of the existing paths or creates a cycle of length equal to the number of cities.
Young Theo, an orphan, has been raised in a small town, Dorning, by a printer named Anton. After the pair accepts a job from a travelling salesman they are investigated by Cabbarus' men, who declare their job illegal and proceed to destroy their press. In the ensuing scuffle and chase, Theo attacks a soldier and Anton is shot and killed. With no one else to turn to, Theo takes to the countryside, eventually meeting up with the men who hired him and Anton for the printing job: Count Las Bombas, a con artist, and his dwarf driver/partner Musket.
Chester was born Cecil Victor Manser in Eastbourne, Sussex. His first job after leaving education was as a grocer's errand boy, but he won talent competitions for his musical instrument playing and singing. Working as a travelling salesman for an embroidery company, Chester realised he had the gift of the gab and decided to become a professional comedian. Known as "Cheerful"per Russell Davies, (Show) BBC Radio 2, Sunday 15 April 2007: common form of nickname "Cheeky" is incorrect Charlie Chester, he was well known to British audiences in the 1940s from his BBC radio show Stand Easy.
Up until the Islamic revolution the region had a subsistence economy – all food was produced within the villages and the surplus was bartered with items supplied by travelling salesman. Most women spent winter months weaving carpets using raw material which were locally produced. Rainfed agriculture on the steep slopes had severely eroded the farms and productivity had dropped to an unsustainable low level, and the inhabitants had to supplement their income by taking seasonal construction jobs in Tehran. After the revolution, thanks to the construction of roads giving accessibility to larger town markets, livestock production became the dominant mode of the region's economy.
Photograph of Anna Markowitz On August 4, 1907, the 24-year-old pawn broker's daughter, from Covington, Kentucky and her travelling salesman boyfriend, from Indianapolis, were walking along a lonely road near the National Soldiers' Home, accompanied by Anna's younger sister, Bertha. As they reached a completely isolated spot in McCabe Park and started chatting with each other, suddenly a man crept up behind Cohan and struck him with a baton. Surprised, Abe turned around, only to be shot twice in the stomach. The attacker then turned towards the sisters, but the frightened Bertha ran off panicked to call the sheriff.
Metaheuristics are used for combinatorial optimization in which an optimal solution is sought over a discrete search-space. An example problem is the travelling salesman problem where the search-space of candidate solutions grows faster than exponentially as the size of the problem increases, which makes an exhaustive search for the optimal solution infeasible. Additionally, multidimensional combinatorial problems, including most design problems in engineeringTomoiagă B, Chindriş M, Sumper A, Sudria-Andreu A, Villafafila-Robles R.

Wilhelm Hansen painted by Julius Paulsen in 1926 Hansen married Henny Nathalie Soelberg Jensen (5 May 1870-1951), a daughter of miller and later travelling salesman Carl S. J. (1831-1908) and Christiane Henriette Pouline Cathrine Dyrhauge (1831-91), on 30 October 1891 in Frederiksberg. He was created a Knight in the Order of the Dannebrog in 1909, was awarded the Cross of Honour in1921 and was created a 2n-ckass Cmmander of the Order of the Dannebrog in 1922. He died in a traffic accident on 4 February 1936 and is buried at Vestre Cemetery in Copenhagen.
He was a visiting scholar at the Institute for Advanced Study in 2002-03.Institute for Advanced Study: A Community of Scholars He was awarded the Gödel Prize for his work on the PCP theorem in 2001 and again in 2010 for the discovery (concurrently with Joseph S. B. Mitchell) of a polynomial time approximation scheme for the Euclidean travelling salesman problem. In 2008 he was inducted as a Fellow of the Association for Computing Machinery.ACM: Fellows Award / Sanjeev Arora In 2011 he was awarded the ACM Infosys Foundation Award, given to mid-career researchers in Computer Science.
Davidson was born in Cohoes in New York in 1900, the son of a travelling salesman, Matthew H. Davidson and his wife Laura (Sutherland). He studied at the University of Pennsylvania graduating in 1923, and taking successively a Master's (1924) and Doctoral degree in anthropology (1928). He was appointed instructor at his alma mater, remaining there, apart from a brief stint at the University of Buffalo for the academic year 1932-1932, until 1946. He spent a year at the University of Oregon before accepting a professorship at the University of Washington where he taught until his untimely death three years later.
The problem is NP-hard, so there is no known algorithm for solving this problem in polynomial time, and even small instances may require long computation time. It was also proven that the problem does not have an approximation algorithm running in polynomial time for any (constant) factor, unless P = NP. The travelling salesman problem may be seen as a special case of QAP if one assumes that the flows connect all facilities only along a single ring, all flows have the same non-zero (constant) value. Many other problems of standard combinatorial optimization problems may be written in this form.
Following this discovery, he pried off his mothers wedding ring, which Peter Sr. had bought for her back in Germany, and pawned it. After graduating from petty crime into more serious offenses, the Gusenberg brothers teamed up with Dean O'Banion, Earl "Hymie" Weiss, George "Bugs" Moran and other members of the North Side Gang. Although Peter Jr. and his brother had little formal education, they both learnt to speak German and English. He later married a German-Irish woman Myrtle Coppleman Gorman and did not let her know about his criminal activities, keeping her under the ruse that he worked as a travelling salesman.
The story was first published in Leipzig in 1912 and dedicated "to Miss Felice Bauer", and in subsequent editions "for F." In 1912, Kafka wrote "Die Verwandlung" ("The Metamorphosis", or "The Transformation"), published in 1915 in Leipzig. The story begins with a travelling salesman waking to find himself transformed into an , a monstrous vermin, being a general term for unwanted and unclean animals. Critics regard the work as one of the seminal works of fiction of the 20th century. The story "In der Strafkolonie" ("In the Penal Colony"), dealing with an elaborate torture and execution device, was written in October 1914, revised in 1918, and published in Leipzig during October 1919.
The Threshold are a fictional organisation who appeared in the Doctor Who Magazine comic strip based on the long-running British science fiction television series Doctor Who. The Threshold were created by the "partnership" of Abraham White, a travelling salesman, and the Pariah, a living weapon of great power created on Gallifrey many years ago, but was soon cast out by Rassilon as it had developed a mind of its own and rebelled. During a final battle with Rassilon, its containment sphere crashed to Earth, where it was discovered by Abraham. Offering him power and immortality, the Pariah persuaded Abraham to merge with her core being.
A problem is NP- complete if, roughly speaking, it is in NP and is not easier than any other NP problem. Many combinatorial problems, such as the Knapsack problem, the travelling salesman problem, and the Boolean satisfiability problem are NP- complete. For all these problems, the best known algorithm has exponential complexity. If any one of these problems could be solved in polynomial time on a deterministic machine, then all NP problems could also be solved in polynomial time, and one would have P = NP. it is generally conjectured that with the practical implication that the worst cases of NP problems are intrinsically difficult to solve, i.e.
A figure illustrating the vehicle routing problem The vehicle routing problem (VRP) is a combinatorial optimization and integer programming problem which asks "What is the optimal set of routes for a fleet of vehicles to traverse in order to deliver to a given set of customers?". It generalises the well-known travelling salesman problem (TSP). It first appeared in a paper by George Dantzig and John Ramser in 1959, in which the first algorithmic approach was written and was applied to petrol deliveries. Often, the context is that of delivering goods located at a central depot to customers who have placed orders for such goods.
This routing problem is equivalent to the travelling salesman problem, which is NP complete, and therefore not amenable to a perfect solution in a reasonable time. One practical routing algorithm is to pick the pin farthest from the center of the board, then use a greedy algorithm to select the next-nearest unrouted pin with the same signal name. Once routed, each pair of nodes in a net is rewritten to become a wire, in a "wire-list." As the signal-pin list is rewritten as a wire-list, the program can assign attributes in the records to indicate whether a wire is top or bottom.
Philip Oliver Goldsmith (1890-1947) started out as a travelling salesman for Raphaels opticians, before opening an opticians at 60 Poland Street specialising in handmade spectacles-frames of real tortoiseshell. His son Charles (1914-1991) joined him in 1930, and during the Second World War, the firm supplied spectacles to the armed forces whilst catering to civilians. Audrey Hepburn in Breakfast at Tiffany's wearing a pair of Oliver Goldsmith 'Manhattan' sunglasses, 1961 In 1947, following Philip's death, Charles took his company's name as his own, and became chairman. As Oliver Goldsmith, he used press coverage and celebrity endorsements to publicise the company and their creative designs.
This was the premiere episode of a new BBC series Comedy Playhouse, which became an important proving ground for many successful TV comedy series. In 1962, Sykes played his first starring film role, being a travelling salesman in the comedy Village of Daughters, set in an Italian village, but featuring a mostly British cast including John Le Mesurier (who was at that time married to Hattie Jacques), and Roger Delgado. This was followed by a supporting role in the MGM British comedy, Kill or Cure, starring Terry-Thomas with a cast of British comedy stalwarts including one of the first film appearances by Ronnie Barker.
On graduating at the age of 16 he was employed by the National Union of Teachers as an advertising clerk, among other duties organising tours for holidaying teachers and accompanying tours of French battlefields. He later worked on the NUT's magazine The Schoolmaster. During the Great Depression he was made redundant more than once; other jobs included compiling ships' equipment inventories for Tankers Ltd and being a travelling salesman of silks and satins. Never very dedicated to his paid employment, Knight spent long lunch hours exploring London and its second hand bookstalls and antique shops and taking photographs (a passion encouraged by his brother-in-law).
The Glaholm and Robson manufacturing plant quickly proved a success and, in the mid-1860s, it employed a young Samuel Storey as a travelling salesman. Glaholm and Storey shared the same Radical and Liberal ideals and, some 10 years later, they went on to become two of the founding members of the Sunderland Echo newspaper.Sunderland Daily Echo and Daily Post: March 19, 1888Sunderland Daily Echo, March 23, 1880 Glaholm was also involved in several other businesses, including the Wreath Quay Forge, the Wear Pottery at Southwick, Sunderland, and the Phoenix Iron Foundry in Coronation Street, Sunderland. He eventually retired from the Hendon Ropery in 1878.
He learned that the police had heard of the plan and were lying in wait and managed to extricate his men from the situation without being caught. In 1868, he left Cockcroft's printing firm to work full-time for the IRB, as organising secretary and arms agent for England and Scotland, posing as a travelling salesman as cover. Although he was wanted by the authorities from 1867, they did not grasp his importance to the IRB. In 1869, authorities obtained a letter that Davitt had written to IRB member Arthur Forrester, urging him not to go through with the execution of a suspected informer.
To make ends meet, he took a job as a travelling salesman with a Bologna necktie company. The couple's plight resulted in news coverage across the United States, and a sympathetic reverend at the Central Church of Christ in Salem, Oregon even called Negrini personally to offer him a job as his assistant, but Negrini turned it down because his fiancée was happy to remain in Italy. Young was released from jail a few days later; deputy police chief Gabriele Mundo stated that an Italian psychiatrist had examined Young and found her "sane in mind and body", and that no charges would be pressed.
The title character is a shoeshine boy who travels back 100 years in time by means of a magic trunk and meets Zachariah Gibson, a travelling salesman and showman who peddles elixirs and tonics. Episodes are based on the pair's travels between the worlds of the 1870s and 1970s. Both characters face challenges in their respective times - Timothy is an orphan who squats in an abandoned warehouse and makes a living shining shoes and doing odd jobs at a neighbourhood diner owned by Wilma. He is bullied by the neighbourhood thug, Barney, who demands $5 from Timothy for the right to work on "his" corner.
Airport), are brought back for one-off specials several years after the series concluded. David Brent (Gervais), forcibly made redundant at the end of the second series, is now a travelling salesman of cleaning supplies. Tim Canterbury (Martin Freeman) and Gareth Keenan (Mackenzie Crook) are still working at the offices of Wernham Hogg, and former Wernham Hogg receptionist Dawn Tinsley (Lucy Davis) now lives in Florida, though is flown back to Britain by the documentary crew to reunite with her old colleagues. The episodes won various awards, including two British Academy Television Awards, a Royal Television Society award, and a Television Critics Association (America) award.
Up until Islamic revolution the village had a subsistence economy – all food was produced within the village and the surplus was bartered with items supplied by travelling salesman. Rainfed agriculture on the steep slopes had severely eroded the farms and productivity had dropped to unsustainable low level, and the inhabitants had to supplement their income by taking seasonal construction jobs in Tehran. After revolution, thanks to the construction of roads and accessibility of larger town markets, livestock production became the dominant mode of the village economy. However, the quarrels about grazing rights didn't allow Industrial animal agriculture and the efforts of Hüseyn Ismayli, a prominent local businessman, in this regard ended in failure.
However, for approximation ratios even closer to 1 than this factor, a later approach of (based on tree-decomposition but not on planar separators) provides better tradeoffs of time versus approximation quality. Similar separator-based approximation schemes have also been used to approximate other hard problems such as vertex cover.; . use separators in a different way to approximate the travelling salesman problem for the shortest path metric on weighted planar graphs; their algorithm uses dynamic programming to find the shortest tour that, at each level of a separator hierarchy, crosses the separator a bounded number of times, and they show that as the crossing bound increases the tours constructed in this way have lengths that approximate the optimal tour.

He was born in Kuppenheim, Germany, the son of a cattle dealer. At the age of 14 he traveled to the USA at the invitation of family friend Aaron Lehman who had immigrated to Jackson, Mississippi. Initially, Dreyfus worked as a travelling salesman selling picture frames, but by the mid-1890s worked on Tin Pan Alley in New York City where he worked closely with songwriter Paul Dresser and transcribed song arrangements. Within a few years he had secured a post with the publishing firm set up by Thomas B. Harms (1860-1906), arranging, plugging songs, and doing some songwriting; his song "Cupid's Garden", published under the pseudonym Max Eugene, was successful in 1901.
Travelling salesman Milton Lumky informs Bruce of a warehouse full of imported, Japanese-made surplus typewriters, and so Stevens drives to Seattle to see this potential bounty for himself. He belatedly discovers that the typewriters all have Spanish language keyboards, and so he tries to pass these hot potatoes down along the line to his former warehouse employer. He reveals his nefarious intentions to Susan, who passes the information onto the warehouse chain which nevertheless decides to take them off his hands at a fair but unprofitable price for Bruce. He then enters a period of waffling and indecision, ultimately deciding to try altering all of the machines himself and selling them at the shop.
Combinatorial optimization is a topic that consists of finding an optimal object from a finite set of objects.. In many such problems, exhaustive search is not tractable. It operates on the domain of those optimization problems in which the set of feasible solutions is discrete or can be reduced to discrete, and in which the goal is to find the best solution. Typical problems are the travelling salesman problem ("TSP"), the minimum spanning tree problem ("MST"), and the knapsack problem. Some research literature considers discrete optimization to consist of integer programming together with combinatorial optimization (which in turn is composed of optimization problems dealing with graph structures) although all of these topics have closely intertwined research literature.
After the war Armin worked at various locations around the London areas, as manager of a furniture company based in Camden Town, London, and then as a market demonstrator. During the late 1940s and early 1950s, while still living in central London, he became father to four children, one of whom died soon after birth. He relocated in 1958 to Yorkshire to follow a new profession as a travelling salesman selling furniture polish, and then a few years later as an encyclopaedia salesman. In 1960 Armin moved to Nottingham, and moved back to London in 1965, where he worked as a civilian driver for the police and a guard for a security firm.
Such a method is described below. Using a shortcut heuristic on the graph created by the matching below # Find a minimum spanning tree for the problem # Create duplicates for every edge to create an Eulerian graph # Find an Eulerian tour for this graph # Convert to TSP: if a city is visited twice, create a shortcut from the city before this in the tour to the one after this. To improve the lower bound, a better way of creating an Eulerian graph is needed. By triangular inequality, the best Eulerian graph must have the same cost as the best travelling salesman tour, hence finding optimal Eulerian graphs is at least as hard as TSP.
In September 1949, Billingham joined Third Division North side Carlisle United, where he spent two seasons and scored 17 goals in 64 league matches. He transferred to Southport in March 1951 and was almost ever-present during his four years with the Haig Avenue club, making 150 appearances and scoring 37 goals. Billingham was released by Southport at the end of the 1954–55 season and moved into non-league football with Nelson, where he played for two years before eventually retiring from the game in 1957 at the age of 42. Following his retirement, he worked as a travelling salesman and also had a spell as a coach at Padiham before returning to live in Daventry, Northamptonshire, where he died on 7 October 1981, aged 66.
Optimization of a solution involves evaluating the neighbours of a state of the problem, which are new states produced through conservatively altering a given state. For example, in the travelling salesman problem each state is typically defined as a permutation of the cities to be visited, and the neighbors of any state are the set of permutations produced by swapping any two of these cities. The well-defined way in which the states are altered to produce neighboring states is called a "move", and different moves give different sets of neighboring states. These moves usually result in minimal alterations of the last state, in an attempt to progressively improve the solution through iteratively improving its parts (such as the city connections in the traveling salesman problem).
There exist inputs to the travelling salesman problem that cause the Christofides algorithm to find a solution whose approximation ratio is arbitrarily close to 3/2. One such class of inputs are formed by a path of vertices, with the path edges having weight , together with a set of edges connecting vertices two steps apart in the path with weight for a number chosen close to zero but positive. All remaining edges of the complete graph have distances given by the shortest paths in this subgraph. Then the minimum spanning tree will be given by the path, of length , and the only two odd vertices will be the path endpoints, whose perfect matching consists of a single edge with weight approximately .
The Denmark Feist is descended from a single dog acquired by the Slade family of Chatham, Virginia in 1917, supposedly the dog was bartered from a travelling salesman for three opossum hides, a large raccoon and a wagon wheel. The family were so impressed with the hunting abilities of this dog that they used him as the foundation sire of a line of dogs. In 1984 Mark Slade, with friend Dennis Willis, unveiled these dogs as a breed, in 1986 the DenMark Treeing Feist Association was formed. The Denmark Feist is used to hunt feral pig, bobcat and squirrel, they are said to be silent hunters that can hunt game on the ground or run the game into trees for the hunter to shoot.
In many problems, a greedy strategy does not usually produce an optimal solution, but nonetheless a greedy heuristic may yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time. For example, a greedy strategy for the travelling salesman problem (which is of a high computational complexity) is the following heuristic: "At each step of the journey, visit the nearest unvisited city." This heuristic does not intend to find a best solution, but it terminates in a reasonable number of steps; finding an optimal solution to such a complex problem typically requires unreasonably many steps. In mathematical optimization, greedy algorithms optimally solve combinatorial problems having the properties of matroids, and give constant-factor approximations to optimization problems with submodular structure.
Jonathan Rose, Oxford Dictionary of National Biography, Oxford University Press, 2004, accessed 24 April 2013 He received a basic schooling and in his early teens he was taken on by Hatchards bookshop in Piccadilly as an errand-boy. Four years later, in 1899, Cape joined the London office of the American publishers Harper and Brothers, where he worked, successively, as clerk, general utility man and travelling salesman, first in the provinces and later in London. In 1904 he joined the publishing house of Duckworth as London traveller, and from 1911 as manager. In 1914, on the outbreak of the Great War, he took over the sole charge of the business when the proprietor, Gerald Duckworth, was absent on war duties.
In 1899, the company filed suit in Ohio court against Frank Torrence, a former employee and travelling salesman of Brown Brothers and against Bucher and Bucher Company of Ohio. The suit alleged that Torrence and Bucher conspired to offer a substandard 5-cent cigar, by the trade name of "La Camerita", to under-cut Brown Brothers by deceiving the customers who were interested in buying Brown Brothers' premium 10-cent cigar by the similar name of "Carmencita". The suit alleged that "La Camerita" was a "fanciful name invented and adopted by the defendant because of its close resemblance to the trade-mark of the plaintiff" (Brown Brothers). The suit further alleged that the former salesman, Torrence was an irresponsible person financially.
Jack Rice (May 14, 1893 – December 14, 1968) was an American actor best known for appearing as the scrounging, freeloading brother-in-law in Edgar Kennedy's series of short domestic comedy films at the RKO studio, and also as "Ollie" (aka "Oliver Merton" and "Oliver Shaw") in around a dozen of Columbia Pictures's series of the Blondie comic strip. Born in Michigan to Dr. John Rice (1858-1921) and Mrs. Eugenia Rice, née Kerwick,(1874-1897), Jack Rice began his career as a stage actor some time after the end of the First World War; he had previously worked as a travelling salesman in Grand Rapids. His stage credits included the annual road company tours of The Passing Show (1922-1925).
Knapsack problem: The ants prefer the smaller drop of honey over the more abundant, but less nutritious, sugar Ant colony optimization algorithms have been applied to many combinatorial optimization problems, ranging from quadratic assignment to protein folding or routing vehicles and a lot of derived methods have been adapted to dynamic problems in real variables, stochastic problems, multi- targets and parallel implementations. It has also been used to produce near- optimal solutions to the travelling salesman problem. They have an advantage over simulated annealing and genetic algorithm approaches of similar problems when the graph may change dynamically; the ant colony algorithm can be run continuously and adapt to changes in real time. This is of interest in network routing and urban transportation systems.
During the rescue, we see that the entire town of Fairville, Pepper, Freckles, and Bella (while in their prison cell), travelling salesman Gordon, the staff of the snake farm, the hairdressers, Penny King, and Grizzly Bear Daniels (who have found each other and are relaxing in Grizzly's hot tub) are watching the news broadcast, that went national when Joe got involved. When Pee-wee asks Joe, "What about the party?", Joe responds, "Pee-wee, we are the party", and then shows Pee-Wee a miniature version of Fairville he created, reflecting one of Pee-Wee's models he saw earlier. Pee-Wee returns to his job at Dan's Diner, where he shows the Fairville residents some of the items he acquired during his trip.
As a practical substitute for an exact formula to determine the length of the shortest path, the Beardwood- Halton-Hammersley Theorem derived a simple asymptotic formula for the shortest length when n is large. The travelling salesman problem can involve either fixed or random points distributed over a certain region. The Theorem established that the shortest length between random points is asymptotically equal to a non-random function of n. For large n the distinction between the random and the non-random versions of the problem effectively vanishes. David L. Applegate described this in 2011 as a “famous result,” and said “The remarkable theorem of Beardwood-Halton-Hammersley has received considerable attention in the research community, ”with demonstrated uses in probability theory, physics, operations research and computer science.
The Christofides algorithm or Christofides–Serdyukov algorithm is an algorithm for finding approximate solutions to the travelling salesman problem, on instances where the distances form a metric space (they are symmetric and obey the triangle inequality).. It is an approximation algorithm that guarantees that its solutions will be within a factor of 3/2 of the optimal solution length, and is named after Nicos Christofides and Anatoliy I. Serdyukov, who discovered it independently in 1976. Up until 2020, this was the best approximation ratio that has been proven for the traveling salesman problem on general metric spaces (although there were better approximations are known for some special cases). In July 2020, Karlin, Klein, and Gharan released a preprint with a new algorithm that they announced has an approximation ratio of 1.5-10−36.
During a visit by a travelling salesman, Uncle Checco, h catches a glimpse in the car, of a photo of a nude woman, and the vision, together with his fantasies of being at the wheel of a vehicle that travels daily throughout the wider world of the countryside below, disturbs him. It provokes his desire, and also his fears of leaving the security of the monastery. While working in the fields one day, a schoolteacher is bitten by a snake, and pleads with him to save her. He kills the snake (symbol of the primal temptation) and, when he explains to her that the venom must be sucked out through an incision, proceeds to suck her upper calf, spitting the poison out, yet massaging her legs in a frenzy of barely disguised ardour.
A relatively short-lived upsurge in the number of peddlers was witnessed in the period following the second World War, when the wartime manufacturing boom came to an abrupt end, and returning soldiers finding themselves unable to secure suitable work, turned to peddling which generally offered a decent income.Buck, D.S., Deaf Peddler: Confessions of an Inside Man, Washington, Gallaudet University Press, 2000 pp 4-5 In the United States, the travelling salesman became a stock character in countless jokes. Such jokes are typically bawdy, and usually feature small town rubes, farmers and other country folk, and frequently another stock character, the farmer's daughter.Buck, D.S., Deaf Peddler: Confessions of an Inside Man, Washington, Gallaudet University Press, 2000 pp 5-8 Throughout much of Europe, suspicions of dishonest or petty criminal activity was long associated with peddlers and travellers.
Jan Karel Lenstra (2017) Jan Karel Lenstra (born 19 December 1947, in Zaandam) is a Dutch mathematician and operations researcher, known for his work on scheduling algorithms, local search, and the travelling salesman problem. Lenstra received his Ph.D. from the University of Amsterdam in 1976, advised by Gijsbert de Leve.. He then became a researcher at the Centrum Wiskunde & Informatica, where he remained until 1989. After taking positions at the Eindhoven University of Technology (where he became Dean of the Faculty of Mathematics and Computer Science) and the Georgia Institute of Technology, he returned to CWI as its director in 2003. He stepped down in 2011, and at that time became a CWI Fellow..

Former homicide detective Mark Mendelson said the investigation would become "the largest Toronto has undertaken". Criminologist and Western University professor Michael Arntfield said that the alleged method of disposal suggested a sophisticated killer who had developed his craft and, as most serial killers begin in their 20s, the crimes could go back several decades and represent the longest run of a serial killer on record. McArthur's past as a travelling salesman suggested to John Bradford, a forensic psychiatrist and expert on serial murders, that police might have a province-wide investigation ahead of them. Toronto crime journalist James Dubro said the allegations suggest McArthur was the deadliest known serial killer in Toronto and the "most prolific" gay serial killer in Canada. On February 8, police announced that they had found the remains of three more people in planters from the Leaside home, and that one of the six sets of remains belonged to Andrew Kinsman, identified through fingerprints.
The Oxford companion to World War II, by Ian Dear, Michael Richard, Daniel Foot During the war, he worked as a railway labourer and dispatcher in Kostomlaty, near Nymburk, an experience reflected in one of his best-known works, Closely Observed Trains (). He worked variously as an insurance agent (1946–1947), a travelling salesman (1947–1949) and a manual labourer alongside the graphic artist Vladimír Boudník in the Kladno steelworks (1949–1952), an experience that inspired the "hyper-realist" texts he was writing at the time. After a serious injury, he worked in a recycling mill in the Prague district of Libeň as a paper packer (1954–1959), before working as a stagehand (1959–1962) at the S. K. Neumann Theatre in Prague (today Divadlo pod Palmovkou). Bohumil Hrabal painted among his beloved cats on the "Hrabal Wall" in Prague Hrabal lived in the city from the late 1940s onward, for much of it (1950–1973) at 24 Na Hrázi ul.
Mainwaring was born in 1885 to Edmund Mainwaring and is a pompous, blustering figure with an overdeveloped sense of his importance, fuelled by his social status in Walmington-on-Sea as the bank manager and his status as Captain and commander of the local Home Guard volunteer unit. He became commander of his home guard unit by saying that he had served as a captain in the last British conflict, despite serving 'somewhere in the Orkneys' during the Great War and only being deployed to France in 1919, the year after the armistice was signed. He was later officially designated as the Captain by the GHQ, in the episode "Room at the Bottom", after his brief reduction in rank. Despite his claim to be the son of a master tailor, it is revealed that his father was a poor draper and a heavy drinker, as is his profligate brother, Barry, who is a travelling salesman specialising in novelty toys.
Three years after the documentary that made them famous, a different documentary crew revisits the office to see what the staff members are doing now. After being made redundant from Wernham Hogg, David Brent (Ricky Gervais) is now a travelling salesman who, following a failed single release of a cover of "If You Don't Know Me By Now," leeches off what little fame he has in a series of demeaning nightclub appearances alongside minor celebrities (such as Howard from the Halifax ads and Bubble from Big Brother). Dawn Tinsley (Lucy Davis) lives in Florida, trapped in a miserable existence with fiancé Lee (Joel Beckett), who is bouncing from job to job as they live with his sister rent-free and hidden from immigration authorities. In the office, Gareth Keenan (Mackenzie Crook) is now the general manager and Tim Canterbury (Martin Freeman) is still trapped in a job he hates with an obnoxious, pregnant desk-mate Anne (Elizabeth Berrington).
The travelling salesman problem asks to find the shortest cyclic tour of a collection of points, in the plane or in more abstract mathematical spaces. Because the problem is NP-hard, algorithms that take polynomial time are unlikely to be guaranteed to find its optimal solution; on the other hand a brute-force search of all permutations would always solve the problem exactly but would take far too long to be usable for all but the smallest problems. Threading a middle ground between these too-fast and too-slow running times, and developing a practical system that can find the exact solution of larger instances, raises difficult questions of algorithm engineering, which have sparked the development of "many of the concepts and techniques of combinatorial optimization". The introductory chapter of the book explores the limits of calculation on the problem, from 49-point problems solved by hand in the mid-1950s by George Dantzig, D. R. Fulkerson, and Selmer M. Johnson to a problem with 85,900 points solved optimally in 2006 by the Concorde TSP Solver, which Cook helped develop.
Wood was also responsible for the Confessions series of novels and their film adaptations, written under the pseudonym Timothy Lea. They are Confessions of a Window Cleaner, Confessions of a Driving Instructor, Confessions from a Holiday Camp, Confessions From a Hotel, Confessions of a Travelling Salesman, Confessions of a Film Extra, Confessions From the Clink, Confessions of a Private Soldier, Confessions From the Pop Scene (adapted into the movie Confessions of a Pop Performer), Confessions From a Health Farm, Confessions From the Shop Floor, Confessions of a Long Distance Lorry Driver, Confessions of a Plumber's Mate, Confessions of a Private Dick, Confessions From a Luxury Liner, Confessions From a Nudist Colony, Confessions of a Milkman, Confessions of an Ice Cream Man and Confessions From a Haunted House. Wood told an interviewer for The Independent in 2013: "The books, and later the films, got terrible reviews, but they were successful, and success was its own currency". Wood told Penthouse that each Confessions book took approximately five weeks to complete.
The NP-hardness of the unweighted longest path problem can be shown using a reduction from the Hamiltonian path problem: a graph G has a Hamiltonian path if and only if its longest path has length n − 1, where n is the number of vertices in G. Because the Hamiltonian path problem is NP- complete, this reduction shows that the decision version of the longest path problem is also NP-complete. In this decision problem, the input is a graph G and a number k; the desired output is "yes" if G contains a path of k or more edges, and no otherwise.. If the longest path problem could be solved in polynomial time, it could be used to solve this decision problem, by finding a longest path and then comparing its length to the number k. Therefore, the longest path problem is NP-hard. The question "does there exist a simple path in a given graph with at least k edges" is NP-complete.. In weighted complete graphs with non-negative edge weights, the weighted longest path problem is the same as the Travelling salesman path problem, because the longest path always includes all vertices..
