Reinforcement learning with reputation-based adaptive exploration promotes cooperation

An Li, Wenqiang Zhu, Chaoqian Wang, Longzhao Liu et autres

Reinforcement learning provides a framework for studying how individuals adjust their behavior through repeated interaction and feedback in social dilemmas. In Q-learning, exploration controls how often agents choose actions other than those favored by their current learned Q-values. Yet, the existing models …

Inhibition of explosive transitions in spreading dynamics by nonlinear higher-order adaptation

Longzhao Liu, Hongwei Zheng, Zhihao Han, Shaoting Tang

The coevolution of structure and dynamics, known as adaptation, is a fundamental property in various systems and drives diverse emergent behaviors. However, the adaptation in most works primarily stems from pairwise situations, which is insufficient to capture ubiquitous higher-order characteristics of real …

Identifying vulnerable nodes for hypergraph dismantling via higher-order competition dynamics

Yajing Hao, Longzhao Liu, Xin Eric Wang, Zhihao Han et autres

Network dismantling aims to identify a node removal sequence that can rapidly destroy network connectivity, which is an important problem for understanding the structural fragility of complex systems and designing intervention strategies. Existing studies mainly focus on pairwise networks or assume weak-deletion …

Emergent dilemma and periodic oscillation in the nonlinear interplay between epidemic and behavior

Longzhao Liu, Hongwei Zheng, Yajing Hao, Qun Wang et autres

Human behaviors, particularly non-pharmaceutical interventions (NPIs), are dynamically coupled with epidemic spreading. While prior studies mainly assume a linear interplay, real-world behavioral evolution is driven by nonlinear responses and social influence. Here, we incorporate these multifaceted mechanisms into a co-evolutionary model and …

Stereotyping by strategy standing diversifies cooperation patterns in indirect reciprocity

Ming Wei, Xin Wang (91924), Wenqiang Zhu, Longzhao Liu et autres

Indirect reciprocity explains how cooperation evolves through social reputations. People observe others, assign reputations, and condition their future actions on these assignments. This process is cognitively demanding, and stereotyping offers a simpler alternative by replacing individual-level reputation with group-level information. Theoretical models …

Indirect reciprocity beyond pairwise interactions

Ming Wei, Xin Wang, Junyu Lu, Longzhao Liu et autres

Cooperation in groups underpins collective responses to challenges from climate governance to public goods provision, yet how moral evaluation sustains it remains poorly understood. Indirect reciprocity -- cooperating to build a good reputation -- is well characterized for pairwise interactions, but real …
