A Model-Based Reinforcement Learning Algorithm for Multi-Agent Cooperation Nash Equilibrium With Unstable Communication

Solving Nash equilibrium is important to multi-agent systems, in which the communication is an important factor. However, many proposed reinforcement learning (RL) based algorithms take into account the communication factors by assuming stable communication conditions, which does not hold in the real environment. In this brief, we analyze the effect of a typical RL algorithm in the cases of unstable communication and communication failure, which causes information loss between agents, leading to isolation of agents and affecting algorithm convergence. Then, we propose a model-based RL algorithm to solve Nash equilibrium for multi-agent systems when agents are isolated, and prove its convergence and rationality through mathematical proofs. The simulations results show the effectiveness of the proposed algorithm.
