Abstract:

This study establishes a dual-threshold $N$-player snowdrift game model with heterogeneous benefits and nonlinear time costs from the perspective of benefit heterogeneity and exponential discounting of time preferences. We develop an Aspiration-Fermi hybrid mechanism by linearly coupling the Aspiration update rule with the PW-Fermi rule, and subsequently construct the corresponding evolutionary dynamics based on the mean dynamic principle. Numerical simulations and comparative analyses reveal that heterogeneous benefits, exponential nonlinear time costs, and the Aspiration-Fermi hybrid mechanism significantly enhance cooperation. This work provides new perspectives for studying the evolution of cooperation in complex societies.

Key words: Aspiration-Fermi hybrid mechanism, heterogeneous benefits benefits, exponential time costs, dual-threshold snowdrift game
