论文摘要
社交网络具有无规律的财产和社区结构，生活中的许多问题具有公共物品的特征，例如资源短缺。由于个人的不同偏好，存在采用异质策略更新网络中规则的个人。我们调查了使用公共物品游戏的无规模社区网络中合作的演变以及多个战略更新规则的影响。在这里，考虑了两种类型的策略更新规则，这些规则是成对比较规则和志向驱动的规则。进行数值模拟并呈现相应的结果。我们发现社区结构促进了公共物品游戏中合作的出现。同时，合作者的频率与两个策略更新规则的比例之间存在“ U”形状关系。随着两个策略更新规则比例的差异，成对比较规则似乎更敏感。与志向驱动的规则相比，成对比较规则在促进合作中起着更重要的作用。我们的工作可能有助于了解社交网络中合作的发展。
Social networks have a scale-free property and community structure, and many problems in life have the characteristic of public goods, such as resource shortage. Due to different preferences of individuals, there exist individuals who adopt heterogeneous strategies updating rules in the network. We investigate the evolution of cooperation in the scale-free community network with public goods games and the influence of multiple strategy updating rules. Here, two types of strategy updating rules are considered which are pairwise comparison rules and aspiration-driven rules. Numerical simulations are conducted and presented corresponding results. We find that community structure promotes the emergence of cooperation in public goods games. In the meantime, there is a "U" shape relationship between the frequency of cooperators and the proportion of the two strategy updating rules. With the variance in the proportion of the two strategy updating rules, pairwise comparison rules seem to be more sensitive. Compared with aspiration-driven rules, pairwise comparison rules play a more important role in promoting cooperation. Our work may be helpful to understand the evolution of cooperation in social networks.
