Mutation mitigates finite-size effects in spatial evolutionary games
Chen Shen, Zhixue He, Lei Shi +1
Agent-based simulations are essential for studying cooperation on spatial networks. However, finite-size effects -- random fluctuations due to limited network sizes -- can cause ce…
Unbiased third-party bots lead to a tradeoff between cooperation and social payoffs
Zhixue He, Chen Shen, Lei Shi +1
The rise of artificial intelligence (AI) offers new opportunities to influence cooperative dynamics with greater applicability and control. In this paper, we examine the impact of…
Indirect punishment can outperform direct punishment in promoting cooperation in structured populations
Yujia Wen, Zhixue He, Chen Shen +1
Indirect punishment traditionally sustains cooperation in social systems through reputation or norms, often by reducing defectors' payoffs indirectly. In this study, we redefine in…
Cooperative bots exhibit nuanced effects on cooperation across strategic frameworks
Zehua Si, Zhixue He, Chen Shen +1
The positive impact of cooperative bots on cooperation within evolutionary game theory is well documented; however, existing studies have predominantly used discrete strategic fram…
Beyond a binary theorizing of prosociality
Chen Shen, Zhixue He, Hao Guo +4
A stylized experiment, the public goods game, has taught us the peculiar reproducible fact that humans tend to contribute more to shared resources than expected from economically r…
Constructive agents nullify the ability of destructive agents to foster cooperation in public goods games
Yuting Dong, Zhixue He, Chen Shen +2
Existing studies have revealed a paradoxical phenomenon in public goods games, wherein destructive agents, harming both cooperators and defectors, can unexpectedly bolster cooperat…
