On the Approximation of Nash Equilibria in Sparse Win-Lose Games

Abstract

We show that the problem of finding an approximate Nash equilibrium with a polynomial precision is PPAD-hard even for two-player sparse win-lose games (i.e., games with 0,1-entries such that each row and column of the two n×n payoff matrices have at most O(log n) many ones). The proof is mainly based on a new class of prototype games called Chasing Games, which we think is of independent interest in understanding the complexity of Nash equilibrium.
