TY - JOUR ID - citeulike:1745215 L3 - citeulike-article-id:1745215 N2 - We propose a model of evolutionary snowdrift game with N-person interactions and study the effects of multi-person interactions on the emergence of cooperation. An exact N-th–order equation for the equilibrium density of cooperators x* is derived for a well-mixed population using the approach of replicator dynamics. The results show that the extent of cooperation drops with increasing cost-to-benefit ratio and the number N of interaction persons in a group, with x*~1/N for large N. An algorithm for numerical simulations is constructed for the model. The simulation results are in good agreement with theoretical results of the replicator dynamics.
