The problem has been excessively studied[1][2][3][4][5][6] and a vast array of methods have been introduced to either ﬁnd the optimal tour or a good less time consuming approximation. Webtraveling salesman problem, an optimization problem in graph theory in which the nodes (cities) of a graph are connected by directed edges (routes), where the weight of an edge indicates the distance between two cities. The problem is to find a path that visits each city once, returns to the starting city, and minimizes the distance traveled. The only known … ctl time

WebThe 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 ...
