Center node: "on the computation of strategically equivalent rank 0 games"
  Abstract: It has been well established that in a bimatrix game, the rank of the matrix formed by summing the payoff (or cost) matrices of the players has an impact on the runtime of the algorithms that converge to a Nash equilibrium of the game. In this paper, we devise a fast linear time algorithm that exploits strategic equivalence between bimatrix games to identify whether or not a given bimatrix game is strategically equivalent to a zero-sum game, and if it is, then we present an algorithm that computes a strategically equivalent zero-sum game.
