Small-world vs scale-free network
WebScale-free networks are also small-world networks, because (i) they have clustering coefficients much larger than random networks (2) and (ii) their diameter increases … WebFeb 4, 2003 · In contrast to the diameter of regular random networks or small-world networks, which is known to be d∼ln N, we show, using analytical arguments, that scale-free networks with 2< λ<3 have a much smaller diameter, behaving as d∼ln ln N. For λ= 3, our analysis yields d ∼ln N /ln ln N, as obtained by Bollobas and Riordan, while for λ >3, d∼ln N.

We find that scale free networks with 2 < λ < 3 have diameter d ∼ lnlnN and thus can be considered as “ultra small world” networks.

WebAbstract. In this chapter we will introduce two famous network models that arose much interest in recent years: The small-world model of Duncan Watts and Steven Strogatz [615] and scale-free or power-law networks, first presented by the Faloutsos brethren [201] and filled with life by a model of Albert- László Barabási and Réka Alberts [60].
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 ... hillary duceyWebFeb 23, 2024 · was found that the World Wide Web is in fact a scale-free network; that is, the connectivity has a power-law distribution with a heavy tail.

If failures occur at random, and the vast majority of proteins are those with a small degree of connectivity, the likelihood that a hub would be affected is small.

Small-world networks can also be introduced with time-delay, which will not only produce fractals but also chaos under the right conditions, or transition to chaos in dynamics networks.
