% where @W = \sum_{ij} B_{ij} \delta(g_i,h_j)@ is the number of edges that
% are inside modules. Alternatively, @Q_r \equiv \frac{W-T}{W+T}@ where
% @T@ is the number of edges that are between modules.  In other words, 
% this quantity maps the relative difference of edges that are
% within modules to those between modules on a scale 
% from 1 (all edges are within modules) to @-1@ (all edges are between modules). 
% This measure allows to compare the output o
