Payoffs and perception mediate environmental feedback in an N-player trust game with Q-learning

Trust develops through learning, while collective behavior can alter the environment in which later decisions are made. Reinforcement-learning models describe adaptation, and eco-evolutionary models describe behavior-environment feedback, but how an endogenous environment changes trust through material incentives and p...

An Evolutionary Computation Framework for Multi-Agent Q-Learning with Mean-Field Environmental Feedback

Multi-agent reinforcement learning in networked populations is governed by the interaction between individual adaptation, local encounters, and changing environmental conditions. To study this interaction, we formulate a coupled learning--environment model in which agents update stateless $Q$-values on a fixed graph, w...
