Self-Play PSRO: Toward Optimal Populations in Two-Player Zero-Sum Games

no code implementations13 Jul 2022 Stephen Mcaleer, JB Lanier, Kevin Wang, Pierre Baldi, Roy Fox, Tuomas Sandholm

Instead of adding only deterministic best responses to the opponent's least exploitable population mixture, SP-PSRO also learns an approximately optimal stochastic policy and adds it to the population as well.

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.
