Enhanced cooperation in the N-person iterated snowdrift game through tag mediation

This paper investigates whether tags can elevate cooperation levels in N-player iterated evolutionary snowdrift games. Tags give agents the ability to form groups that can prosper under certain circumstances. Previous work showed tags promote cooperation in iterated prisoner's dilemma games but no work has seen if they enhance cooperation in snowdrift games. We studied different tag models used in prisoner dilemma games and found they also promote cooperation in snowdrift games. We also discuss the relationship between tags and the red queen effect.
