No need to use Cbc - look at some of the *Test.cpp's in Cgl and
just<br>
<br>
OsiClpSolverInterface solver - read model and initial solve - then
create GMI cut generator and generate cuts.<br>

<div>Hi<br>
<br>
</div>
I need to generate only GMI cuts from optimal LP tableau. I
don't want to solve the problem, only need to see the actual
cuts in one iteration!<br>
<br>
</div>
What would be the easiest way?<br clear="all">
