221
222   The default settings correspond to the fast variants of LMBM and MBM. MBM
223   never  produces  a  more accurate approximation than LMBM for the same
224   state-space decomposition. However, the corresponding statement does not
225   hold for the fast versions. (That is, FastMBM will occasionally outperform
226   FastLMBM.) To get the slower, but more accurate versions of LMBM and MBM use
227   the following settings:
228     * set ardc_constrain_method 1
229     * set ardc_constrain_reorder no
230     * set ardc_abstract_pseudo_input 0
