Informational bounds on equilibria (a survey)

Abstract

Query complexity and communication complexity of equilibria have been actively studied in the past decade. Recent progress in these fields of informational complexity has led to a quite good understanding of equilibria. This survey summarizes the established results for the three most common solution concepts: Nash equilibria, correlated equilibria, and coarse correlated equilibria. The survey provides a high-level idea of the techniques that are utilized to deduce recently developed lower bounds on Nash equilibria.
