[Cbc] How to iteratively cutting the current optimal solution

Pierre,

There may be a way to do something.  I will try and put up a new example in
a few days which does something close to what you want.

Hello,

I would like to know if cbc currently supports row addition after a solve,
so as to cut the optimal solution and proceed to the next one. The purpose
is to find a series of close-to-optimal solutions, without solving the
whole ILP each time. Thanks in advance.

Cheers,

Pierre Le Bodic
