The paper looks at tag-based cooperation within abstract simulation models. Previous models of this kind have been shown to either have ‘programmed in’ cooperation or to be vulnerable to “strong cheaters”.  Previous work by the author included a model of social specialisation and cooperation, but where only a single dominant tag-group arose at any one time and where cooperation eventually collapsed.  Here a multi-patch version of this model is explored and show to not to collapse but seed itself indefinitely.  Furthermore, the model seems to be resistant to significant levels of strong cheaters.
