Shaping the learning signal in a combined Q-learning rule to improve structured cooperation
Chunpeng Du, Zongyang Li, Yali Zhang +2
Q-learning provides a standard reinforcement learning framework for studying cooperation by specifying how agents update action values from repeated local interactions outcomes. Al…
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…
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…
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…
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…
How Committed Individuals Shape Social Dynamics: A Survey on Coordination Games and Social Dilemma Games
Chen Shen, Hao Guo, Shuyue Hu +3
Committed individuals, who features steadfast dedication to advocating strong beliefs, values, and preferences, have garnered much attention across statistical physics, social scie…
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…
Robust and Efficient Network Reconstruction in Complex System via Adaptive Signal Lasso
Lei Shi, Jie Hu, Libin Jin +3
Network reconstruction is important to the understanding and control of collective dynamics in complex systems. Most real networks exhibit sparsely connected properties, and the co…
Social physics
Marko Jusup, Petter Holme, Kiyoshi Kanazawa +12
Recent decades have seen a rise in the use of physics methods to study different societal phenomena. This development has been due to physicists venturing outside of their traditio…
Decomposing Excess Commuting: A Monte Carlo Simulation Approach
Yujie Hu, Fahui Wang
Excess or wasteful commuting is measured as the proportion of actual commute that is over minimum (optimal) commute when assuming that people could freely swap their homes and jobs…
