The glpk simplex solver is not perfect. Try to disable scaling (by default glpsol performs automatic scaling); if this will not help, try to disable the lp presolver and then steepest-edge pricing. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
