Abstract

The Hawk-Dove game is a two-player game-theoretic micro-model that can be used to investigate the evolution of cooperative behaviour in many-agent systems. Individual agents have a stochastic strategy in the form of a continuous-valued probability of playing a non-cooperative ``hawk'' strategy and a large system of agents is formulated on various spatial grids of different dimensionalities and sizes of neighbourhoods. We investigate the approach of the spatial Hawk-Dove game towards a well-mixed equilibrium state as the player interaction neighbourhood size is increased. We explore metrics for assessing the closeness of the system to being well-mixed and compare results from numerical simulations with theoretical predictions for a well-mixed system, where spatial isolation effects ought to be irrelevant.

Keywords: hawk-dove game; cooperation; mixed strategy; stochastic strategy.
