A Traveling Salesman Problem Library

Juni 24, 2021 Posting Komentar

We consider a variant of the classical symmetric Travelling Salesman Problem in which the nodes are partitioned into clusters and the salesman has to visit at least one node for each cluster. This problem is to find the shortest path that a salesman should take to traverse through a list of cities and return to the origin city.
