Zero-sum Random Games on Directed Graphs

Abstract

This paper considers a class of two-player zero-sum games on directed graphs whose vertices are equipped with random payoffs of bounded support known by both players. Starting from a fixed vertex, players take turns to move a token along the edges of the graph. On the one hand, for acyclic directed graphs of bounded degree and sub-exponential expansion, we show that the value of the game converges almost surely to a constant at an exponential rate dominated in terms of the expansion. On the other hand, for the infinite dd-ary tree that does not fall into the previous class of graphs, we show convergence at a double-exponential rate in terms of the expansion.
