TSP problem is a well-known problem in the multi-objective evolutionary optimization domain. Recently, I encountered a case that needs to use an existing algorithm for solving the problem. It is well known that both numerical optimization algorithms, such as EDA, and combinatorial optimization algorithms, such as GA, can be used to solve this problem. However, to the best of my knowledge, there is no comparative study on the multi-objective TSP problem with regard to different paradigms. Therefore, is there any recommendation on existing multi-objective TSP methods?
