I think it would need a major re-write of Sbb. On the other hand it would
be fairly easy to provide callbacks which might allow more flexibility
along the lines of ClpEventHandler. One could collect maximum nodes,
solutions, seconds etc into SbbEventHandler and then let the user derive a
class from this which could do whatever is wanted and then reset the
maximum value.
If you can describe what you want to do or send me something I can see how
much work it would be.

[Coin-discuss] sbb/resolve a MIP?
Hi.
I am using sbb and wondering whether it is possible to resume a call
to SbbModel::branchAndBound() after it has stopped reaching
SbbAmximumSeconds?
For the cases where I don't change anything in the model this should
be possible. Does anyone know how?
Cheers
