THE TRAVELING SALESMAN PROBLEM 2 1 Statement Of The Problem The traveling salesman problem involves a salesman who must make a tour of a number of cities using the shortest path available and visit each city exactly once and only once and return to the original starting point. For each number of cities n ,the number of paths which must be ... sequence. Therefore, the problem consists of finding a sequence that minimizes the total positioning time. This leads to a traveling salesman problem. iv. Computer wiring (Lenstra & Rinnooy Kan, 1974) reported a special case of connecting components on a computer board. Modules are located on a comput er board and a given subset of pins has toExample- The following graph shows a set of cities and distance between every pair of cities- If salesman starting city is A, then a TSP tour in the graph is-A → B → D → C → A Cost of the tour = 10 + 25 + 30 + 15 = 80 units In this article, we will discuss how to solve travelling salesman problem using branch and bound approach with ...
