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