The problem is to find a path that visits each city once, returns to the starting city, and minimizes the distance traveled.The traveling salesperson problem can be modeled as a graph. Specifically, it is typical a directed, weighted graph. Each city acts as a vertex and each path between cities is an edge. Instead of distances, each edge has a weight associated with it. In this model, the goal of the traveling salesperson problem can be defined as finding a path ...Output –. Here, the TSP Tour is 0-2-1-3-0 and the cost of the tour is 48.
