[Lemon-user] A quick question

[Yongjia Song]

Hi, all,

I am a new user of lemon. I find it a little inconvenient when using lemon
in this situation. Suppose I would like to run a maxflow from s to t, and
the graph is constructed beforehand.

Now I could not figure out a way to specify node s and node t efficiently,
(Naturally, we can just specify nodes by their index, but it does not seem
to have such kind of index in lemon)

unless I specify them in the first place or write the nodes in a .lgf file.

So is there an efficient way to specify nodes in the graph?

Thanks,
