A Donation Heterogeneity Public Goods Game on High Clustering Coefficient and Adjustable Power-Law Network

Based on the "triangular structure" and "internal evolution" evolution mechanism, an adjustable power-law network model with high clustering coefficients is presented. This model has the same characteristics as the standard scale-free networks with the power-law degree distribution, but it has the high clustering. Heterogeneity public goods game is studied on this network model. According to the central node, the difference of investment in public goods game is decided by the number of cooperators in its neighbors and two neighbors. The heterogeneity degree of the input difference is adjusted by a regulation factor. The simulation proves that the heterogeneous configuration model can quickly reach the Nash equilibrium, and an optimal range of the regulation factors can promote the cooperation boom for the new network model.
