Abstract

Cooperative behavior can contribute to the development of society. Evolutionary game theory is a fundamental framework for studying cooperative behavior. This article explores the evolutionary dynamics of the three-faced strategy, which can demonstrate its different attribute behaviors according to different types of objects encountered by paying a certain role-switching cost. When three-faced individuals encounter cooperators, they will show defection behavior; when they interact with defectors, they will show punishment behavior; and when they meet the same kind, they will show cooperative behavior. The results show that the presence of three-faced individuals can effectively suppress defectors when the cost of role-switching is small or when the government gives relatively high incentives. Moreover, the moderate role-switching cost enhances the maintenance and emergence of cooperators. Additionally, as the system is in a stable state, which is full of three-faced individuals, the behavior displayed by the three-faced individuals at this time is consistent with that of the cooperators, which also promotes cooperative behavior in the population to some extent.
