WebAug 25, 2024 · python-tsp is a library written in pure Python for solving typical Traveling Salesperson Problems (TSP). It can work with symmetric and asymmetric versions. … WebA TSP with a fixed starting point and no return to start, can be solved as an ordinary TSP with all the in-going arcs to the starting point having a cost of zero. That way the return to the starting point is "for free" and the TSP solver only focuses on the remaining part of the tour, giving you an optimal "open TSP".
