Well Supported Approximate Equilibria in Bimatrix Games: A Graph Theoretic Approach
Abstract. We study the existence and tractability of a notion of approximate equilibria in bimatrix games, called well supported approximate Nash Equilibria (SuppNE in short). We p...

Efficient Algorithms for Constant Well Supported Approximate Equilibria in Bimatrix Games
Abstract. In this work we study the tractability of well supported approximate Nash Equilibria (SuppNE in short) in bimatrix games. In view of the apparent intractability of constr...

Computing Equilibria in Bimatrix Games by Parallel Support Enumeration
We consider the problem of computing all Nash equilibria in bimatrix games (i.e., nonzero-sum two-player noncooperative games). Computing all Nash equilibria for large bimatrix ga...

The complexity of uniform Nash equilibria and related regular subgraph problems
We investigate the complexity of finding Nash equilibria in which the strategy of each player is uniform on its support set. We show that, even for a restricted class of win-lose ...

Structure of Extreme Correlated Equilibria
We exhibit the rich structure of the set of correlated equilibria by analyzing the simplest of polynomial games: the mixed extension of matching pennies. We show that while the co...
