Small world coefficient
WebThe term small world refers to the idea that the preponderance of vertices have both local clustering and short paths to other vertices. The modifier phenomenon refers to the unexpected fact that so many graphs that arise in practice are sparse, exhibit local clustering, and have short paths. 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. One possibility is that small-world networks are more robust to … See more Applications to sociology The advantages to small world networking for social movement groups are their resistance to change due to the filtering apparatus of using highly connected nodes, and its better effectiveness in relaying information … See more In another example, the famous theory of "six degrees of separation" between people tacitly presumes that the domain of discourse is the set of people alive at any one time.

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.
