Tsp problem.

Abstract. In Chapter 15 we introduced the Traveling Salesman Problem (TSP) and showed that it is NP -hard (Theorem 15.42). The TSP is perhaps the best-studied NP -hard combinatorial optimization problem, and there are many techniques which have been applied. We start by discussing approximation algorithms in Sections 21.1 and 21.2.Jan 4, 2024 · Travelling Salesman Problem (TSP)– Given a set of cities and the distance between every pair of cities as an adjacency matrix, the problem is to find the shortest possible route that visits every city exactly once and returns to the starting point. The ultimate goal is to minimize the total distance travelled, forming a closed tour or circuit. Multiple variations on the problem have been developed as well, such as mTSP, a generalized version of the problem and Metric TSP, a subcase of the problem.
