topological growth as well as by weight change. In addition, we introduce the weighted assortativity coefficient, which … generalizes the assortativity coefficient of a topological network, to measure the tendency of having a high-weighted link between … weight evolution. Most importantly, by studying the weighted assortativity coefficient, we found that both topologically …

assortativity coefficient r is determined and it is shown that the nonlinear Barabási–Albert network is assortative (disassortative …) if α<1(α>1) and no assortative only when α=1. In the limit α→−∞ the assortativity coefficient can be exactly calculated …
