Evolutionary analysis of multi-player snowdrift game with cost sharing under Aspiration–Fermi hybrid rule

This paper firstly constructs a multi-player snowdrift game with all players’ cost sharing once the snowdrift is removed for a fairness. Secondly, an Aspiration–Fermi hybrid rule is proposed to derive an extended average abundance function via Markov chain evolutionary processes. Besides, extensive numerical simulations well verify theoretical results. Our findings show that both cost sharing and the Aspiration–Fermi hybrid rule significantly promote the cooperation by enhancing the average abundance in multi-person snowdrift game. By comparison with the existing woks, our proposed model and hybrid strategy-update rule provide novel insights into the evolution of cooperation in multi-person games.
