 All other routines are modifications of this original routine
 done by MUMPS developers over the years (1996-2012).
 .
   MUMPS_AMD_ELT is a modification 
   designed to handle amalgamated and compressed
   graphs and was developed in 1999 by Patrick Amestoy 
   in the context of the PARASOL project (1997-1999).
 .
   MUMPS_HAMD is a modification 
   designed to take into account a halo in the graph. 
   The graph is composed is partitioned in two types of nodes
   the so called internal nodes and the so called halo nodes.
   Halo nodes cannot be selected the both the initial degrees 
   and updated degrees of internal node should be taken 
   into account.  
   This routine also referred to as HALOAMD in MUMPS comments
   is used for both Schur functionality and in the coupling with 
   partitioners such as SCOTCH.
   This code was developed for MUMPS platform 
   by Patrick Amestoy between 1997 and 1999.
 .
   MUMPS_HAMF4 is a major modification of MUMPS_HAMD 
   since metric used to select pivots in not anymore the 
   degree but an approximation of the fill-in.
   In this approximation 
   all cliques of elements adjacent to the variable are deducted.
   Written by Patrick Amestoy between 1999 and 2000.
   It is also used by F. Pellegrini in SCOTCH since 2000.
 .
   MUMPS_QAMD: modified version of reference AMD routine MUMPS_ANA_H 
   designed to automatically detect and exploit dense or quasi dense
   rows in the reduced matrix at any step of the minimum degree.

 the Licensor without any other express or tacit warranty, other than
 that provided for in Article 9.2 and, in particular, without any
 warranty as to its commercial value, its secured, safe, innovative or
 relevant nature.
 .
 Specifically, the Licensor does not warrant that the Software is free
 from any error, that it will operate without interruption, that it
 will be compatible with the Licensee's own equipment and software
 configuration, nor that it will meet the Licensee's requirements.
 .
 9.4 The Licensor does not either expressly or tacitly warrant that the
 Software does not infringe any third party intellectual property right
 relating to a patent, software or any other property right. Therefore,
 the Licensor disclaims any and all liability towards the Licensee
 arising out of any or all proceedings for infringement that may be
 instituted in respect of the use, modification and redistribution of
 the Software. Nevertheless, should such proceedings be instituted
 against the Licensee, the Licensor shall provide it with technical and
 legal assistance for its defense. Such technical and legal assistance
 shall be decided on a case-by-case basis between the relevant Licensor
 and the Licensee pursuant to a memorandum of understanding. The
 Licensor disclaims any and all liability as regards the Licensee's use
 of the name of the Software. No warranty is given as regards the
 existence of prior rights over the name of the Software or as regards
 the existence of a trademark.
