MAXQ is a new framework for multi-agent reinforcement learning. But the MAXQ framework cannot decompose all subtasks into more refined hierarchies and the hierarchies are difficult to be discovered automatically. In this paper, a multi-agent hierarchical reinforcement learning approach, named OptMAXQ, by integrating Options into MAXQ is presented. In the OptMAXQ framework, the MAXQ framework is used to introduce knowledge into reinforcement learning and the Option framework is used to construct hierarchies automatically. The performance of OptMAXQ is demonstrated in two-robot trash collection task and compared with MAXQ. The simulation results show that the OptMAXQ is more practical than MAXQ in partial known environment.
