WebIn a graph with a "small world" topology, nodes are highly clustered yet the path length between them is small. Small world networks which have already been identified are the collaboration graph of actors in feature films, the neural network of the nematode worm C. elegans, and the electrical grid of the western United States [1]. WebApr 5, 2012 · The resulting graphs were between the regular and random in their structure and are referred to as small-world (SW) networks. SW networks are very close structurally to many social networks in that they have a higher clustering and almost the same average path than the random networks with the same number of nodes and edges.
