[Lemon-user] A question using lemon library

[Yongjia Song]

Hi all,

I am a new user of Lemon library. Now I am doing MIP with cplex and I just
want to use Lemon for my maxflow solver.(As far as I know, solve maxflow in
a LP is much worse than using a flow algorithm)

So I construct my own graph structure(better fit the syntax of cplex), and
every time I would like to solve a maxflow problem, I will construct a
capacity vector, and the graph remains exactly the same.

To do that, I initiate a lemon graph in the first place, and call a function
that use the lemon graph instance and the capacity vector(an stl vector),
say

double maxflow(SmartDigraph g, vector<double> capacity)
{
}

The question is, I could not directly use the functions in g. There are
always errors. Can anyone give me a short example using lemon just as a
solver using its algorithms?

Thanks,
