Greedy-based Value Representation for Efficient Coordination in Multi-agent Reinforcement Learning

no code implementations29 Sep 2021 Lipeng Wan, Zeyang Liu, Xingyu Chen, Han Wang, Xuguang Lan

Due to the representation limitation of the joint Q value function, multi-agent reinforcement learning (MARL) methods with linear or monotonic value decomposition can not ensure the optimal consistency (i. e. the correspondence between the individual greedy actions and the maximal true Q value), leading to instability and poor coordination.
