Abstract

The eligibility trace is one of the basic mechanisms in reinforcement learning to handle delayed reward. In this paper, we have used meta-heuristic method to solve hard combinatorial optimization problems. Our proposed solution introduce Ant-Q learning method to solve Traveling Salesman Problem (TSP). The approach is based on population that use positive feedback as well as greedy search and suggest ant reinforcement learning algorithms using eligibility traces which is called replace-trace methods(Ant-TD(λ)). Although replacing traces are only slightly, they can produce a significant improvement in learning rate. We could know through an experiment that proposed reinforcement learning method converges faster to optimal solution than ACS and Ant-Q.
