Can We Find Nash Equilibria at a Linear Rate in Markov Games?

Zhuoqing Song, Jason D. Lee, Zhuoran Yang

We study decentralized learning in two-player zero-sum discounted Markov games where the goal is to design a policy optimization algorithm for either agent satisfying two propertie…

Sparsified Block Elimination for Directed Laplacians

Richard Peng, Zhuoqing Song

We show that the sparsified block elimination algorithm for solving undirected Laplacian linear systems from [Kyng-Lee-Peng-Sachdeva-Spielman STOC'16] directly works for directed L…
