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…
Enhancing social cohesion with cooperative bots in societies of greedy, mobile individuals
Lei Shi, Zhixue He, Chen Shen +1
Addressing collective issues in social development requires a high level of social cohesion, characterized by cooperation and close social connections. However, social cohesion is…
Mixed strategy approach destabilizes cooperation in finite populations with clustering coefficient
Zehua Si, Zhixue He, Chen Shen +1
Evolutionary game theory, encompassing discrete, continuous, and mixed strategies, is pivotal for understanding cooperation dynamics. Discrete strategies involve deterministic acti…
Impact of Committed Minorities: Unveiling Critical Mass of Cooperation in the Iterated Prisoner's Dilemma Game
Zhixue He, Chen Shen, Lei Shi +1
The critical mass effect is a prevailing topic in the study of complex systems. Recent research has shown that a minority of zealots can effectively drive widespread cooperation in…
Simple bots breed social punishment in humans
Chen Shen, Zhixue He, Lei Shi +2
Costly punishment has been suggested as a key mechanism for stabilizing cooperation in one-shot games. However, recent studies have revealed that the effectiveness of costly punish…
