Dear all,


I am using igraph to detect community structures of a Chinese power grid. I have invoked the igraph_community_fastgreedy() successfully, and I can see the modularity vector as well. However, I cannot understand the result of “merge” at all. It always shows

Is there anybody who can explain it to me? In fact, I only want to record the detail communities (say, the real node sets of each community) when the modularity property reaches the maximum.


By the way, I have registered to the mail list yesterday, but I have not received any confirm letter yet. Is there anything wrong about the mail list?


Thanks a lot!
