(TSP) is the problem of finding a Hamiltonian cycle with minimum costs of a graph. If the graph has n nodes, a tour T is a per-mutation T = (x 1,x
Asymmetric and symmetric. In the symmetric TSP, the distance between two cities is the same in each opposite direction, forming an undirected graph. This symmetry halves the number of possible solutions. In the asymmetric TSP, paths may not exist in both directions or the distances might be different, forming a … See more 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 … See more The TSP can be formulated as an integer linear program. Several formulations are known.
