No, it wouldn't, because GLP_ENODFS means 'no dual feasible solution exists' while GLP_UNBND also assumes primal feasibility. Moreover, in case of GLP_UNBND the simplex solver provides additional information suitable for generating rows while GLP_UNDEF means that no solution information is available. _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
