You can distinguish them by the row type, which is GLP_FR unlike other rows, or by theirs names. If necessary, such rows can be removed from the model with glp_del_rows. > But there is separate function > glp_get_obj_func for accessing obj. fun. coefficients. Coefficients of the very first objective in the model are used as objective coefficients in the problem object. _______________________________________________ Bug-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-glpk
