alpha index

alpha index, α index In network analysis, the ratio of the actual number of circuits in a network to the maximum possible number of circuits in that network. It is given as:α = ^{e − v + p}/_{2v − 5}
×100where e = edges, v = vertices, and p = number of graphs or subgraphs. Values range from 0%—no circuits—to 100%—a completely interconnected network.
