چکیده

In order to solve traveling salesman problems that employed completiontimeshortest as the evaluating rule, an encoding method and improved differential evolution algorithm were proposed. In these methods, real number encoding and roulette wheel selection were adopted for improved differential evolution and neighborhood search operator was devised. It was fit for solving symmetric and asymmetric multiple traveling salesman problem. Asymmetric multiple traveling salesman problems were simulated. By comparison with the results of genetic algorithm and standard differential evolution, it is shown that the improved differential evolution algorithm proposed in this paper is efficient to solve the discrete combinatorial problem, such as optimization of multiple traveling salesman problems.

An Effective Genetic Algorithm for Solving the Multiple Traveling Salesman Problem

The multiple traveling salesman problem (MTSP) involves scheduling m > 1 salesmen to visit a set of n > m nodes so that each node is visited exactly once. The objective is to minimize the total distance traveled by all the salesmen. The MTSP is an example of combinatorial optimization problems, and has a multiplicity of applications, mostly in the areas of routing and scheduling. In this paper,...
