Abstract
In this paper we extend the classical concept of
positional strategies for a mean payoff game to a general mixed
stationary strategy approach, and prove the existence of mixed
stationary Nash equilibria for an arbitrary $m$-player mean payoff
game on graphs. Traditionally, a positional strategy represents a
pure stationary strategy in a classical mean payoff game, where a
Nash equilibrium in pure stationary strategies in general may not
exist. Based on a constructive proof of the existence of specific
equilibria for an $m$-player mean payoff game we propose a new
approach for determining the optimal mixed stationary strategies.
Additionally we characterize and extend the general problem of the
existence of pure stationary Nash equilibria for some special
classes of mean payoff games.
