Evolutionary Dynamics of Reputation-Based Voluntary Prisoner's Dilemma Games
Chen Shen, Zhao Song, Xinyu Wang +4
Cooperation underlies many natural and artificial systems. While voluntary participation can sustain cooperation without informational assumptions, real interactions are rarely ano…
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…
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…
Stability of pairwise social dilemma games: destructive agents, constructive agents, and their joint effects
Khadija Khatun, Chen Shen, Lei Shi +1
Destructive agents, who opt out of the game and indiscriminately harm others, paradoxically foster cooperation, representing an intriguing variant of the voluntary participation st…
