louvain modularity in Graphx seems to have a problem

[muzhi1991]

When compute deltaQ in q method ， deltaQ = k_i_in - (k_i * sigma_tot / M) seems not right. Here M is degree of Graph(2* edge, here may be total edge weight*2). According the paper，we can use relative value of Q to choose neighbor ( that is k_i_in - sigma_tot*k_i/m ). so here M should be replaced by M/2（just m in paper） . is right or am I wrong？

It depends on which version of paper you've red.
