You should call lpx_simplex first to obtain the optimal solution of LP relaxation (which is LP problem, where integer restrictions are omitted). However, in case lpx_intopt this is not needed. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
