Comment (by mgalati):
In the case of pure IP, we typically want to stop the col-gen process
early, so MasterGapLimit=0.01 by default. In the case of pure LP, that
won't work. Now, if the problem is a pure LP, internally, DIP will change
that parameter to 1.0e-8. You will see this message:
{{{
Problem is an LP. Reset param MasterGapLimit = 1e-08
}}}
