[Help-glpk] MIP solver: stopping and continuing

[address@hidden]

Hi all,
I need to stop every n iterations the MIP solver, check if some constraints need
to be added, then continue solving from where I was.

The problem is: I don't mind starting over again when I add a constraint, but I
would like to see the MIP problem continue if I don't add any constraint.

If I just call lpx_integer again, the iterations number increases, but the B&B
tree starts from the beginning.

What do I miss?

Thanks a lot,
Matteo
