About this paper

Haomin Luo, Ersha Li

The authors compare learned reinforcement-learning update rules and feedback routes in cooperative multi-agent tasks. They assess trained pairs alongside focal agents evaluated with held-out partners, and vary physical coupling and training horizon. In Overcooked, coupled MAPPO earns higher self-play return, while coupled Disco103 has higher held-out-bank return and fewer collisions. Results depend on task, horizon, and synthetic partner bank.
