Hi Mr. Sutton thanks for the answer.
I didn't know what was **R :-D**. Now I have readed some links and I have understand that RBGL is not adapt for my project (into the file zip Win Binary I have seen a ..dll file than I thought that I could use more libraries :)).
My goal is to do multi minimum cuts (gomory hu tree algorithm: http://www.corelab.ntua.gr/~syrganis/sources/Gomory-Hu.pdf ).
The min-cut BGL functions give out only the min-cut value, I want to know what edges were cut.
Can you help me?

Sorry for my english ;/
Thanks a lot for your time and for the help.
Bye.
