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 ...

Introduction to Small-World Networks and Scale-Free Networks

WebIn contrast, scale-free topologies are characterised by the presence of small number of highly connected hub nodes and a high number of feebly connected nodes. Presence of … 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. counter height work chairs

WebScale-free networks emerge in the context of a growing network in which new vertices connect preferentially to the more highly connected vertices in the network (5). Scale-free networks are also small-world networks, because (i) they have clustering coefficients much larger than random networks (2) and (ii) The main mechanism to construct small-world networks is the Watts–Strogatz mechanism. 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. Degree–diameter graphs are constructed such that the number of neighbors each vertex in the network has is bounded, while the distance from any given vertex in the network to any other ver… WebApr 7, 2003 · Networks that exhibit a power-law distribution have a lot of nodes with a small degree and a long 'tail' of the distribution where a few nodes have disproportionately large degrees (hubs).

The recipe of Barabási and Albert has been followed by several variations and generalizations and the revamping of previous mathematical works. As long as there is a power law distribution in a model, it is a scale-free network, and a model of that network is a scale-free model.
