WebEnumerate All Solutions of the TSP Cutting Plane Approaches to DFJ A solution of a TSP with n cities derives from a sequence of n decisions, where the kth decision consists of choosing the kth city to visit in the tour The number of nodes (or states) grows exponentially with n At stage k, the number of states is n k k! WebHowever, the TSP is closely related to several of the problem areas discussed before, like 2-matching, spanning tree, and cutting planes, which areas actually were stimulated by ques-tions prompted by the TSP, and often provide subroutines in solving the TSP.
