Changing row/column scale factors may change the basis matrix that would invalidate the current basis factorization stored in glp_prob by the simplex solver, because the factorization is computed for the scaled matrix, not for the original one. However, this affects only efficiency, because if the basis factorization is invalid, the simplex solver will compute it. _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
