Fig. 4From: The configuration model for Barabasi-Albert networksLight point series: function knn(k) for a finite BA2 network according to the formulas of Fotouhi-Rabbat. Dark point series: average of knn(k) over 40 configuration model realizations obtained as in Fig. 3 (but with fixed hubs). The disassortativity for small k is clearly visible, and the slight assortativity for large k is also confirmedBack to article page
