Distributed Multi-Agent Reinforcement Learning Based on Graph-Induced Local Value Functions

no code implementations26 Feb 2022 Gangshan Jing, He Bai, Jemin George, Aranya Chakrabortty, Piyush K. Sharma

Achieving distributed reinforcement learning (RL) for large-scale cooperative multi-agent systems (MASs) is challenging because: (i) each agent has access to only limited information; (ii) issues on convergence or computational complexity emerge due to the curse of dimensionality.
