Small world coefficient
WebJun 12, 2024 · The small world property (high local clustering and short paths) emerges for a small rewiring probability p ranging from 0.001 to 0.1 in Fig 2 in [ 2 ]. For a small p, e.g., p = 0.01, about 1% of the arcs are rewired. Accordingly, the degree of most nodes would be N = 2 K during rewiring and this assumption is not significantly limiting. WebThe small-world coefficient is defined as: sigma = C/Cr / L/Lr where C and L are respectively the average clustering coefficient and average shortest path length of G. Cr and Lr are respectively the average clustering coefficient and average shortest path length of an equivalent random graph.

WebModeling Small World Networks • The ER model for random graphs provided shorter paths between any two nodes in the network. However, the ER graphs have a low clustering … Small-world networks tend to contain cliques, and near-cliques, meaning sub-networks which have connections between almost any two nodes within them. This follows from the defining property of a high clustering coefficient. Secondly, most pairs of nodes will be connected by at least one short path. This … See more A small-world network is a mathematical graph in which most nodes are not neighbors of one another, but the neighbors of any given node are likely to be neighbors of each other. Due to this, most neighboring … See more Small-world properties are found in many real-world phenomena, including websites with navigation menus, food webs, electric power grids, metabolite processing networks, See more It is hypothesized by some researchers, such as Barabási, that the prevalence of small world networks in biological systems may reflect an evolutionary advantage of such an architecture.
