标题： Cooperation dynamics of generalized reciprocity in state-based social dilemmas

摘要： 我们引入了一个框架，用于研究网络社会中的社会困境，其中个体遵循基于广义互惠的简单状态行为机制，该机制根植于“如果被某人帮助，就帮助任何人”的原则。 在这个适用于多种社会困境的通用框架中，包括公共产品、捐赠和雪堆游戏等，我们研究了在各种复杂网络示例上的合作动态。 通过非线性动力系统的角度来解释所研究的模型，我们表明，通过广义互惠的合作总是作为唯一的吸引子出现，在这种情况下总体合作水平达到最大，同时防止了参与个体的剥削。 分析阐明了网络结构的作用，这里由一个局部中心性度量捕捉，该度量唯一地量化了网络结构促进合作的倾向，通过规定微观和宏观层面上表现出的合作程度。 我们通过考虑将捐赠过程与公共产品游戏耦合的交互结构，在一个实际例子中展示了分析的适用性。 显示英文摘要

摘要： We introduce a framework for studying social dilemmas in networked societies where individuals follow a simple state-based behavioral mechanism based on generalized reciprocity, which is rooted in the principle "help anyone if helped by someone". Within this general framework, which applies to a wide range of social dilemmas including, among others, public goods, donation and snowdrift games, we study the cooperation dynamics on a variety of complex network examples. By interpreting the studied model through the lenses of nonlinear dynamical systems, we show that cooperation through generalized reciprocity always emerges as the unique attractor in which the overall level of cooperation is maximized, while simultaneously exploitation of the participating individuals is prevented. The analysis elucidates the role of the network structure, here captured by a local centrality measure which uniquely quantifies the propensity of the network structure to cooperation, by dictating the degree of cooperation displayed both at microscopic and macroscopic level. We demonstrate the applicability of the analysis on a practical example by considering an interaction structure that couples a donation process with a public goods game.
