[igraph] Question about the result of community structure detection

[Zhigang Wu]

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!

 

Best Regards
