Individual Heterogeneous Learning with Global Centrality in Prisoner Dilemma Evolutionary Game on Complex Network

The influence of individual heterogeneity on the evolutionary game has been studied extensively in recent years. Whereas many theoretical studies have found that the heterogeneous learning ability effects cooperation rate, the individual learning ability in networks is still not well understood. It is known that an individual's learning ability is influenced not only by its first order neighbors, hut also by higher order individuals, and even by the whole network. At present, existing methods to represent individual learning ability are based on degree centrality, resulting in ignoring the global centrality of nodes. In this paper, we design a method for describing the heterogeneous learning ability by taking advantage of a pre-factor theta(x) related to the node betweenness. And a parameter alpha is used to tune theta(x). Experiments show that individual heterogeneous learning ability-is effected by global information. Our findings provide a new perspective to understand the important influence of the global attributes of nodes on the evolutionary game. (C) 2020 The Authors. Published lay Atlantis Press SARL.
