Web(iii) β value exceeds 1 for a complicated network structure having more than one circuit. Alpha Index (α): One of the most useful measures of the connectivity of a network, particularly a fairly complex network, is the alpha index (α). The alpha index (α) for a non-planar graph may thus be defined as: α= actual circuit/ maximum circuits.
