WebIt is known that a wide variety of abstract graphs exhibit the small-world property, e.g., random graphs and scale-free networks. Further, real world networks such as the World Wide Web and the metabolic network also exhibit this property.

WebJun 22, 2015 · The Barabási–Albert (BA) model is an algorithm for generating random scale-free networks using a preferential attachment mechanism. The Watts–Strogatz model is a random graph generation model that produces graphs with small-world properties, including short average path lengths and high clustering. Both algorithms are well … WebIn this Letter we study the diameter of scale-free random networks and show that it is signiﬁcantly smaller than the diameter of regular random networks. We ﬁnd that scale free networks with 2 < λ < 3 have diameter d ∼ lnlnN and thus can be considered as “ultra small world” networks.

WebSep 26, 2000 · We present evidence of the occurrence of three classes of small-world networks: ( a) scale-free networks, characterized by a vertex connectivity distribution that decays as a power law; ( b) broad-scale networks, characterized by a connectivity distribution that has a power law regime followed by a sharp cutoff; and ( c) single-scale … WebClustering coefficient. In graph theory, a clustering coefficient is a measure of the degree to which nodes in a graph tend to cluster together. Evidence suggests that in most real-world networks, and in particular social networks, nodes tend to create tightly knit groups characterised by a relatively high density of ties; this likelihood tends ...
