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 … WebA graph G = (V, E) has a small-world property if it has a high clustering coefficient and a small characteristic path length. A high clustering coefficient represents a local connectivity property, typically resulting in a high number of cliques and near-cliques, which denote subnetworks comprising edges between all or almost all vertices. hitrust wikipedia

WebOct 5, 2015 · Small-world networks should have some spatial structure, which is reflected by a high clustering coefficient. By contrast, random networks have no such structure and a low clustering coefficient. Small-world networks are efficient in communicating and similar and thus have a small shortest path length, comparable to that of random networks. falak tak
