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.

To solve the Travelling Salesman Problem (TSP), one needs to first understand the concept of the Hamilton cycle (also referred to as the Hamiltonian cycle). A Hamilton cycle is a graph cycle (closed loop) through a graph that visits each node exactly once (Mathworld, 2022a). This is named after Sir William Rowan Hamilton, who …Therefore, the problem becomes an (n+1)-city symmetric TSP. After solving, just delete dummy point and then the minimum length Hamiltonian path is solved and we can get the TSP path without returning back the start point.The Traveling Salesman Problem, or TSP for short, is one of the most intensively studied problems in computational mathematics. These pages are devoted to the history, applications, and current research of this challenge of finding the shortest route visiting each member of a collection of locations and returning to your starting point. …The Travelling Salesman Problem (TSP) is a well-known optimization problem in computer science and operations research. The problem is defined as follows: given a set of cities and the distances between them, find the shortest possible route that visits each city exactly once and returns to the starting city.
