Lpx_simplex is obsolete and kept only for backward compatibility. Since it does not return LPX_E_BADB (see, for example, the reference manual for glpk 4.11), its behavior must not be changed in more recent versions of the package. Please use glp_simplex instead. _______________________________________________ Bug-glpk mailing list Bug-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/bug-glpk
