Use the option '-o outfile' to write the solution to a file and see kkt optimality conditions printed at the bottom of the sheet. If the solution quality is high or medium for all four conditions, the solution found by glpsol is correct within a tolerance. I cannot check your model without data file. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
