[Cbc] How to iteratively cutting the current optimal solution

Pierre,
If I'm not mistaken, the same topic was discussed on this list (and the Osi list) in July/August, under subject "Several optimal integers solutions". See

Subject: [Cbc] How to iteratively cutting the current optimal solution

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
