AN ANT COLONY SYSTEM FOR TEAM ORIENTEERING PROBLEMS WITH TIME WINDOWS

摘要

This paper discusses a heuristic approach for Team Orienteering Problems with Time Windows. The method we propose takes advantage of a solution model based on a hierarchic generalization of the original problem, which is combined with an Ant Colony System algorithm.rnComputational results on benchmark instances previously adopted in the literature suggest that the algorithm we propose is effective in practice.
