The resulting spatially extended co-evolutionary game exhibits stationary states which are Nash equilibria. After perturbation of these equilibria, avalanches of mutations reestablish a stationary state. Scale-free avalanche distributions are observed that are in accordance with calculations from the Nash equilibria and a confined branching process. The transition from subcritical to critical avalanche dynamics can be traced to a change in the degeneracy of the cooperative macrostate and is observed for many variants of this game.", "revisions": [ { "version": "v1", "updated": "2002-08-14T09:20:01.000Z" } ], "analyses": { "keywords": [ "nash equilibria", "stationary state", "scale-free avalanche distributions", "resulting spatially extended co-evolutionary game", "iterated prisoners dilemma" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
