Computational Complexity of Approximate Nash Equilibrium in Large Games

Computer Science and Game Theory 2014-05-20 v3

Abstract

We prove that finding an epsilon-Nash equilibrium in a succinctly representable game with many players is PPAD-hard for constant epsilon. Our proof uses succinct games, i.e. games whose payoff function is represented by a circuit. Our techniques build on a recent query complexity lower bound by Babichenko.
