9.2. MSKIPARAME: INTEGER PARAMETERS 129<br />

Default value:<br />

-1<br />

9.2.32 MSK IPAR INTPNT OFF COL TRH<br />

Corresponding constant:<br />

MSK IPAR INTPNT OFF COL TRH<br />

Description:<br />

Controls how many offending columns are detected in the Jacobian of the constraint matrix.<br />

1 means aggressive detection, higher values mean less aggressive detection.<br />

0 means no detection.<br />

Possible Values:<br />

Any number between 0 and +inf.<br />

Default value:<br />

40<br />

9.2.33 MSK IPAR INTPNT ORDER METHOD<br />

Corresponding constant:<br />

MSK IPAR INTPNT ORDER METHOD<br />

Description:<br />

Controls the ordering strategy used by the interior-point optimizer when factorizing the Newton<br />

equation system.<br />

Possible values:<br />

• MSK ORDER METHOD APPMINLOC Approximate minimum local fill-in ordering is employed.<br />

• MSK ORDER METHOD EXPERIMENTAL This option should not be used.<br />

• MSK ORDER METHOD FORCE GRAPHPAR Always use the graph partitioning based ordering even<br />

if it is worse that the approximate minimum local fill ordering.<br />

• MSK ORDER METHOD FREE <strong>The</strong> ordering method is chosen automatically.<br />

• MSK ORDER METHOD NONE No ordering is used.<br />

• MSK ORDER METHOD TRY GRAPHPAR Always try the the graph partitioning based ordering.<br />

Default value:<br />

MSK ORDER METHOD FREE
