(a, b) AIA – AIA scale-free networks colored according to the node eigenvector centrality and (c) their node degree distributions. The parameters are: \(k_{min} = 2\), \(k_{max} = 260\), \(\langle k\rangle \simeq 6.8\), \(\zeta \simeq 30.8\), \(N=500\) for (a), and \(k_{min} = 2\), \(k_{max} = 38\), \(\langle k\rangle \simeq 5.2\), \(\zeta \simeq 14.6\), \(N=60\) for (b), respectively. Inset demonstrates approximation of these networks by the power node degree distribution (14) with degree exponent \(\nu \simeq 2.3\).
