438 APPENDIX B. PARAMETERS B.2.29 iparam.intpnt max iterations Corresponding constant: iparam.intpnt max iterations Description: Controls the maximum number of iterations allowed in the interior-point optimizer. Possible Values: Any number between 0 and +inf. Default value: 400 B.2.30 iparam.intpnt max num cor Corresponding constant: iparam.intpnt max num cor Description: Controls the maximum number of correctors allowed by the multiple corrector procedure. negative value means that MOSEK is making the choice. A Possible Values: Any number between -1 and +inf. Default value: -1 B.2.31 iparam.intpnt max num refinement steps Corresponding constant: iparam.intpnt max num refinement steps Description: Maximum number of steps to be used by the iterative refinement of the search direction. A negative value implies that the optimizer Chooses the maximum number of iterative refinement steps. Possible Values: Any number between -inf and +inf. Default value: -1
B.2. IPARAM: INTEGER PARAMETERS 439 B.2.32 iparam.intpnt off col trh Corresponding constant: iparam.intpnt off col trh Description: Controls how many offending columns are detected in the Jacobian of the constraint matrix. 1 means aggressive detection, higher values mean less aggressive detection. 0 means no detection. Possible Values: Any number between 0 and +inf. Default value: 40 B.2.33 iparam.intpnt order method Corresponding constant: iparam.intpnt order method Description: Controls the ordering strategy used by the interior-point optimizer when factorizing the Newton equation system. Possible values: • orderingtype.appminloc Approximate minimum local fill-in ordering is employed. • orderingtype.experimental This option should not be used. • orderingtype.force graphpar Always use the graph partitioning based ordering even if it is worse that the approximate minimum local fill ordering. • orderingtype.free The ordering method is chosen automatically. • orderingtype.none No ordering is used. • orderingtype.try graphpar Always try the the graph partitioning based ordering. Default value: orderingtype.free
