Group formation with split rule in social dilemmas

In this research, we propose group formation that enhances the performance of multiagent systems in the Social Dilemmas. As the mechanisms for group formation, mutual choice mechanism for 2-IPD is extended to that for N-IPD. Furthermore, group split based on the metanorm of mutual choice is introduced. As a result of simulations with an evolutionary approach, we confirm the enhancement of the performance of the systems consisting of self-interest agents.
