Re: [igraph] Joint Membership in Cohesive.blocks

[Gábor Csárdi]

Hi, I think this is easy. Create a matrix with all zeros, then go over
each pair of vertices, and check in which blocks they both appear in
blocks(mwBlocks). Choose the highest cohesion from these blocks. Let
us know if you need more help!

Cheers,
Gabor
