About
MAizeBargAIn is a multi-round bargaining benchmark where agents negotiate over privately valued items under time pressure and outside options, then are assessed game-theoretically against a diverse roster of heuristic and RL opponents. It scores agents not just on raw payoff, but on strategic robustness, efficiency, and fairness using equilibrium-based regret plus welfare and envy-freeness metrics.
