Snowdrift Game on Topologically Alterable Complex Networks

Abstract EN

In order to study the influence of network’s structure on cooperation level of repeated snowdrift game, inthe frame of two kinds of topologically alterable network models, the relation between the cooperation densityand the topological parameters was researched.

The results show that the network’s cooperation density iscorrelated reciprocally with power-law exponent and positively with average clustering coefficient; in otherwords, the more homogenous and less clustered a network, the lower the network’s cooperation level;and the relation between average degree and cooperation density is nonmonotonic; when the average degreedeviates from the optimal value, the cooperation density drops.
