Evolving networks with disadvantaged long-range connections

摘要

We consider a growing network, whose growth algorithm is based on the preferential attachment typical for scale-free constructions, but where the long-range bonds are disadvantaged. Thus, the probability to get connected to a site at distance dd is proportional to dαd^{-\alpha}, where α\alpha is a tunable parameter of the model. We show that the properties of the networks grown with α<1\alpha <1 are close to those of the genuine scale-free construction, while for α>1\alpha >1 the structure of the network is vastly different. Thus, in this regime, the node degree distribution is no more a power law, and it is well-represented by a stretched exponential. On the other hand, the small-world property of the growing networks is preserved at all values of α\alpha .
