Defector-accelerated cooperativeness and punishment in public goods games with mutations
Defector-accelerated cooperativeness and punishment in public goods games with mutations
We study the evolution of cooperation in spatial public goods games with four competing strategies: cooperators, defectors, punishing cooperators, and punishing defectors. To explore the robustness of the cooperation-promoting effect of costly punishment, besides the usual strategy adoption dynamics we also apply strategy mutations. As expected, frequent mutations create kind …
