摘要
This paper discusses a new hybrid solution method for a bi-objective routing problem, namely the bi-objective ring star problem. The bi-objective ring star problem is a generalization of the ring star problem in which the assignment cost has been dissociated from the cost of visiting a subset of nodes. Here, we investigate the possible contribution of incorporating specialized TSP heuristics into a multiobjective evolutionary algorithm. Experiments show that the use of this hybridization scheme allows a strict improvement of the generated sets of non-dominated solutions.
