摘 要:In this paper,we propose a clique-based sparse reinforcement learning(RL) algorithm for solving cooperative tasks.The aim is to accelerate the learning speed of the original sparse RL algorithm and to make it applicable for tasks decomposed in a more general manner.First,a transition function is estimated and used to update the Q-value function,which greatly reduces the learning time.Second,it is more reasonable to divide agents into cliques,each of which is only responsible for a specific subtask.In this way,the global Q-value function is decomposed into the sum of several simpler local Q-value functions.Such decomposition is expressed by a factor graph and exploited by the general maxplus algorithm to obtain the greedy joint action.Experimental results show that the proposed approach outperforms others with better performance.
