Emergence of cooperation: A reputation-modulated reinforcement learning
Chenyang Zhao, Jiqiang Zhang, Li Chen +1
Reputation is widely recognized as a key mechanism for sustaining cooperation. However, most existing game-theoretic models treat reputation primarily as an external factor that mo…
Balancing Multiple Objectives in Urban Traffic Control with Reinforcement Learning from AI Feedback
Chenyang Zhao, Vinny Cahill, Ivana Dusparic
Reward design has been one of the central challenges for real world reinforcement learning (RL) deployment, especially in settings with multiple objectives. Preference-based RL off…
Decoding species coexistence: A reinforcement learning perspective
Kaiwen Jiang, Chenyang Zhao, Shengfeng Deng +3
A central goal in ecology is to understand how biodiversity is maintained. Previous theoretical works have employed the rock-paper-scissors (RPS) game as a toy model, demonstrating…
Evolution of cooperation in a bimodal mixture of conditional cooperators
Chenyang Zhao, Xinshi Feng, Guozhong Zheng +3
Extensive behavioral experiments reveal that conditional cooperation is a prevalent phenomenon. Previous game-theoretical studies have predominantly relied on hard-manner models, w…
