SNEAD: Solving Nash Equilibria with Adversarial Deviation
Abstract/Contents
- Abstract
- We present SNEAD, an extension of an algorithmic framework by McKelvey (1998) under which one can reduce the problem of finding Nash equilibria in finite games to a tractable unified optimization problem. Specifically, we adapt the method to tractably optimize continuous-strategy games and improve asymptotic running time over finite-strategy games. We further prove that convergence of our algorithm to zero loss guarantees a Nash equilibrium in quasiconcave games. Experimentally, our algorithm achieves state of the art performance on a variety of games, even in the face of high-dimensional, complex payoff functions. Finally, we provide supplementary theoretical frameworks which further adapt SNEAD to locate symmetric equilibria or subgame-perfect equilibria with novel algorithmic efficiency.
