Equilibrium stability drives cooperation in Q-learning algorithms

A new research paper explores how equilibrium stability can drive cooperation among Q-learners, particularly in scenarios where exploration does not vanish over time. The study focuses on the repeated Prisoner's Dilemma, analyzing the time-averaged fraction of cooperative strategies played by algorithms that continue to adapt. Researchers derived a boundary condition predicting when non-defection-dominated behavior emerges, which was validated through extensive simulations of epsilon-greedy Q-learning. AI

    Equilibrium stability as a driver of cooperation among Q-learners

    Algorithmic collusion among pricing algorithms has raised concerns about sustained supra-competitive prices and their implications for social welfare. Existing work has largely focused on the probability that reinforcement-learning algorithms converge to cooperative strategies, t…
