WebSep 28, 2024 · Policy-Space Response Oracles (PSRO) is a general algorithmic framework for learning policies in multiagent systems by interleaving empirical game analysis with deep reinforcement learning (DRL). At each iteration, DRL is invoked to train a best response to a mixture of opponent policies. The repeated application of DRL poses an expensive … WebSep 3, 2024 · diversepsro · GitHub Overview Repositories 1 Projects Packages Stars diversepsro Follow Block or Report Popular repositories diverse_psro Public Python 13 4 0 contributions in the last year

Despite this, prior studies of PSRO have been focused on two-player zero-sum games, a regime where in Nash equilibria are tractably computable.
WebPSRO算法流程: 1.随机初始化所有智能体的策略空间 \Pi ,对于策略空间 \Pi 中的每个策略 \pi ,计算对应的期望效用 U^ {\Pi} ,初始化得到元策略 $$ \sigma_i=\operatorname {UNIFORM}\left (\Pi_i\right) $$ 在每个epoch中:进行如下循环(2.和3.) 2.对每个智能体进行循环: (1)从对手的元策略中采样固定策略 \pi_ {-i}\sim \sigma_ {-i} (2)(用 RL ) … WebJul 13, 2024 · 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. As a result, SP-PSRO empirically tends to converge much faster than APSRO and in many games converges in just a few iterations.

WebRectified PSRO is a variant of PSRO in which each learner only plays against other learners that it already beats. We prove by counterexample that Rectified PSRO is not guaranteed to converge to a Nash equilibrium. We also show that Rectified PSRO rarely converges in random normal form games. filati wollgeflüsterWebJun 15, 2024 · Finding approximate Nash equilibria in zero-sum imperfect-information games is challenging when the number of information states is large.
