Re: [igraph] graph with weighted connections between edges

[Tamás Nepusz]

If I understood your problem correctly, you are not dealing with a single 
weighted graph here but an ensemble of _unweighted_ graphs where edges are 
independent and exist with a certain probability, and you are interested in the 
"consensus community structure" of the ensemble. In my opinion, the cleanest  
(but probably very computationally intensive) way of dealing with it would be 
to generate a large number of graph realisations from the ensemble, cluster 
each and every one of them, and then for each pair of vertices, count how many 
times they ended up in the same community.
