You don't need to use the callback until you solve mip with the branch-and-cut method. In case of lp just solve it using a subset of constraints, add violated constraints and/or remove inactive constraints and then re-optimize. _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
