Thank you for your report. Does the solver report infeasibility or optimality? If the latter, how large is the bound violation? Note that in a solution, which is marked as feasible or /optimal, some basic variables may slightly (i.e. within a tolerance) violate their bounds. _______________________________________________ Bug-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-glpk
