In March 2005, the travelling salesman problem of visiting all 33,810 points in a circuit board was solved using Concorde TSP Solver: a tour of length 66,048,945 units was found and it was proven that no shorter tour exists. The computation took approximately 15.7 CPU-years (Cook et al. 2006). Visa mer The travelling salesman problem (also called the travelling salesperson problem or TSP) asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that … Visa mer The TSP can be formulated as an integer linear program. Several formulations are known. Two notable formulations are the Miller–Tucker–Zemlin (MTZ) formulation and the … Visa mer Metric In the metric TSP, also known as delta-TSP or Δ-TSP, the intercity distances satisfy the triangle inequality. A very natural restriction of the TSP is to require that the distances between cities form a Visa mer The origins of the travelling salesman problem are unclear. A handbook for travelling salesmen from 1832 mentions the problem and includes example tours through Germany and Switzerland, but contains no mathematical treatment. The TSP was … Visa mer As a graph problem TSP can be modelled as an undirected weighted graph, such that cities are the graph's vertices, paths are the graph's edges, and a path's distance is the edge's weight. It is a minimization problem starting and finishing … Visa mer The traditional lines of attack for the NP-hard problems are the following: • Devising exact algorithms, which work reasonably fast only … Visa mer The problem has been shown to be NP-hard (more precisely, it is complete for the complexity class FP ; see function problem), and the decision problem version ("given the costs and a … Visa mer WebbSymmetry / Asymmetry. Above the distance is symmetric: from A to B the distance is the same as B to A, this is named sTSP. By default, the TSP is considered sTSP. TSP can also consider asymmetric distances, called …
