Abstract

Recently, network topologies have been predominantly defined by pairwise interactions. However, in human societies and ecosystems, interactions often involve groups of three or more individuals. Here, we investigate the evolution of multiplayer snowdrift game within the framework of scale-free simplicial complexes. We combine four second-order evaluation norms, along with adaptive reputation thresholds that adapt in real-time based on local information with the reputation-based target neighbor selection mechanism, and investigate their impact on cooperative behaviors. Our results indicate that increasing individual reputation sensitivity promotes cooperation under the Shunning, Imagescoring, Simplestanding rules, while cooperation is inhibited with the Sternjudging rule. In addition, cooperation will be suppressed when the number of game players increases from dyadic (two-player) to triadic (three-player) interactions. These results are beneficial to delve into the emergence of cooperation.
