A Policy Resonance Approach to Solve the Problem of Responsibility Diffusion in Multiagent Reinforcement Learning

no code implementations16 Aug 2022 Qingxu Fu, Tenghai Qiu, Jianqiang Yi, Zhiqiang Pu, Xiaolin Ai, Wanmai Yuan

SOTA multiagent reinforcement algorithms distinguish themselves in many ways from their single-agent equivalences.

A Cooperation Graph Approach for Multiagent Sparse Reward Reinforcement Learning

1 code implementation5 Aug 2022 Qingxu Fu, Tenghai Qiu, Zhiqiang Pu, Jianqiang Yi, Wanmai Yuan

Next, based on this novel graph structure, we propose a Cooperation Graph Multiagent Reinforcement Learning (CG-MARL) algorithm, which can efficiently deal with the sparse reward problem in multiagent tasks.
