The Algebra of Assortativity and the Evolution of Cooperation

This paper presents an evolutionary game theoretic analysis of the dynamics of a population of prisoners' dilemma players where the probability of encountering an cooperator is higher for cooperators than for noncooperators. Examples from biological and cultural evolution are presented. There is also a discussion of voluntary matching where one's type is informatively, but imperfectly signalled.subliminal extant Smith economagic gmm
