Global Policy-Space Response Oracles for Two-Player Zero-Sum Games

ArXi:2605.28273v1 Announce Type: new The Policy-Space Response Oracles (PSRO) framework scales equilibrium computation to large zero-sum games by iteratively expanding a restricted strategy set using deep reinforcement learning (DRL). A central challenge is to construct, under limited computational budgets, a small strategy population whose induced game well approximates the full game.
