Specifically, if one can find an efficient (i.e., polynomial-time) algorithm for the traveling salesman problem, then efficient algorithms could be found for all other problems in the NP -complete class. 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.

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.Deleting arcs (7,8) and (10, 9) flips the subpath from 8 to 10. Two TSP tours are called 3-adjacent if one can be obtained from the other by deleting three edges and adding three edges. 3-opt heuristic. Look for a 3-adjacent tour with lower cost than the current tour. If one is found, then it replaces the current tour.While solving the travelling salesman problem (TSP), optimising multiple objectives such as cost, time, and environmental factors adds complexity as solutions need to balance conflicting goals. 5. Combinatorial Complexity. TSP is a combinatorial optimisation problem, which means it involves complicated mathematical calculations …1. Introduction. The traveling salesman problem (TSP) is undoubtedly the most extensively studied problem in combinatorial optimization. In popular language, the TSP can be described as the problem of finding a minimum distance tour of n cities, starting and ending at the same city and visiting each other city exactly once. In spite of …
