Shapley Q-value: A Local Reward Approach to Solve Global Reward Games

Understand

Cooperative game is a critical research area in the multi-agent reinforcement learning (MARL).

• Global reward game is a subclass of cooperative games, where all agents aim to maximize the global reward.
• Credit assignment is an important problem studied in the global reward game.
• Most of previous works stood by the view of non-cooperative-game theoretical framework with the shared reward approach, i.e., each agent being assigned a shared global reward directly.
