Anytime PSRO for Two-Player Zero-Sum Games

no code implementations19 Jan 2022 Stephen Mcaleer, Kevin Wang, John Lanier, Marc Lanctot, Pierre Baldi, Tuomas Sandholm, Roy Fox

PSRO is based on the tabular double oracle (DO) method, an algorithm that is guaranteed to converge to a Nash equilibrium, but may increase exploitability from one iteration to the next.

Pipeline PSRO: A Scalable Approach for Finding Approximate Nash Equilibria in Large Games

2 code implementations NeurIPS 2020 Stephen McAleer, John Lanier, Roy Fox, Pierre Baldi

We also introduce an open-source environment for Barrage Stratego, a variant of Stratego with an approximate game tree complexity of $10^{50}$.
