Abstract: The multiple traveling salesman problem (MTSP) is a well-known combinatorial optimization problem generalized from the traveling salesman problem (TSP). It has been widely and successfully applied. However, it cannot well represent some new application problems due to its identical cities allowing any salesman to visit. We propose a new MTSP called colored traveling salesman problem (CTSP) in which a city of one to multiple colors can be visited by any salesman of a single same color. The basic CTSP can be subdivided into radial CTSP and serial CTSP with respect to different city coloring topology. We formulate the two CTSP as integrated programming models. After analyzing the limitations of their exact solution, we propose several heuristics and evolutionary algorithms with different coding schemes for approximate. Subsequently, they are applied to the adopted datasets for TSP and their performances are compared. We have investigated the job scheduling problems of multi-bridge machining systems by applying the proposed CTSP and methodology. The seminar concludes with a promising outlook of CTSP solutions and new applications.
