WebThe file test/metric_tsp_approx.cpp contains an example of using this TSP approximation algorithm. Notes [1] Since the visitor parameter is passed by value, if your visitor contains state then any changes to the state during the algorithm will be made to a copy of the visitor object, not the visitor object passed in. WebJun 10, 2024 · Travelling Salesman Problem (TSP) is an interesting problem. Problem is defined as “given n cities and distance between each pair of cities, find out the path which visits each city exactly once and come back to starting city, with the constraint of minimizing the travelling distance.”. TSP has many practical applications.
