Topological frustration in evolutionary games

We explore the effects of topological mesoscopic structure in the outcome of evolutionary game dilemmas. Particularizing on the prisoner dilemma and the Stug Hunt we reveal unexpected patterns of cooperation that correspond to topological frustration in the underlying complex network. While the cooperation levels in the iterated PD can be related to the sub-structure of networks at the level of modules or communities, the cooperation outcome of the iterated SH relies on special motifs corresponding to frustrated states. These results can shed light on the evolution of networks and cooperation.
