While earlier works [9, 10] mainly care for asymptotic computational complexity, in recent works, real-life execution time has been a major consideration, motivation for which comes from the enormous size of real-life networks having vertices in the ranges of millions to billions. To achieve eﬃciency, approximate triangle counting

WebActually the defining properties of a 2-BMG are unusual apart from bi-transitivity, and a natural question is whether 2-BMGs also have properties which well fit in structural graph theory. In this paper we show some of such properties. A major result is that if a 2-BMG has no equivalent vertices then each of its orientation is acyclic. WebBeta Index in Graph. Alpha Index in a Graph.

Koether (Hampden-Sydney College) Reﬂexivity, Symmetry, and Transitivity Mon, Apr 1, 2013 13 / 23 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 to be greater than the average probability of a tie randomly established between two nodes (Holland and Leinhardt, 1971; Watts and Strogatz, 1998 ).
