WebThere are two versions of the TSP we will solve: the symmetric and the asymmetric TSP. The symmetric version is one in which the travel costs across routes are the same for both directions, i.e., the cost from A to B is the same as the cost from B to A. The asymmetric version is a TSP in which the cost from one node to the next need not be the ...

Symmetric and Asymmetric TSP

WebProblem Formulation. Formulate the traveling salesman problem for integer linear programming as follows: Generate all possible trips, meaning all distinct pairs of stops. Calculate the distance for each trip. The cost function to minimize is the sum of the trip distances for each trip in the tour. The decision variables are binary, and ... WebData¶. The instances provided come from the TSPLib asymmetric TSP database. They follow the TSPLib explicit format. The number of cities is defined after the keyword “DIMENSION:” and the full distance matrix is defined after the keyword “EDGE_WEIGHT_SECTION”. bingham local authority
