The evolutionary dynamics of the Public Goods game addresses the emergence of cooperation within groups of individuals. However, the Public Goods game on large populations of interconnected individuals has been usually modeled without any knowledge about their group structure. In this paper, by focusing on collaboration networks, we show that it is possible to include the mesoscopic information about the structure of the real groups by means of a bipartite graph. We compare the results with the projected (coauthor) and the original bipartite graphs and show that cooperation is enhanced by the mesoscopic structure contained. We conclude by analyzing the influence of the size of the groups in the evolutionary success of cooperation.
公共物品博弈的演化动态研究了群体内部合作的出现。然而，在对大量相互关联的个体进行建模时，通常不了解他们的群体结构。在本文中，我们通过关注协作网络，展示了通过二分图可以将有关真实群体结构的介观信息包含在内。我们将结果与投影（合著者）和原始二分图进行比较，并表明合作受到包含的介观结构的增强。最后，我们通过分析群体大小对合作进化成功的影响来进行总结。
