130 CHAPTER 9. PARAMETERS 9.2.34 MSK IPAR INTPNT REGULARIZATION USE Corresponding constant: MSK IPAR INTPNT REGULARIZATION USE Description: Controls whether regularization is allowed. Possible values: • MSK OFF Switch the option off. • MSK ON Switch the option on. Default value: MSK ON 9.2.35 MSK IPAR INTPNT SCALING Corresponding constant: MSK IPAR INTPNT SCALING Description: Controls how the problem is scaled before the interior-point optimizer is used. Possible values: • MSK SCALING AGGRESSIVE A very aggressive scaling is performed. • MSK SCALING FREE The optimizer chooses the scaling heuristic. • MSK SCALING MODERATE A conservative scaling is performed. • MSK SCALING NONE No scaling is performed. Default value: MSK SCALING FREE 9.2.36 MSK IPAR INTPNT SOLVE FORM Corresponding constant: MSK IPAR INTPNT SOLVE FORM Description: Controls whether the primal or the dual problem is solved. Possible values:

9.2. MSKIPARAME: INTEGER PARAMETERS 131 • MSK SOLVE DUAL The optimizer should solve the dual problem. • MSK SOLVE FREE The optimizer is free to solve either the primal or the dual problem. • MSK SOLVE PRIMAL The optimizer should solve the primal problem. Default value: MSK SOLVE FREE 9.2.37 MSK IPAR INTPNT STARTING POINT Corresponding constant: MSK IPAR INTPNT STARTING POINT Description: Starting point used by the interior-point optimizer. Possible values: • MSK STARTING POINT CONSTANT The optimizer constructs a starting point by assigning a constant value to all primal and dual variables. This starting point is normally robust. • MSK STARTING POINT FREE The starting point is chosen automatically. • MSK STARTING POINT GUESS The optimizer guesses a starting point. • MSK STARTING POINT SATISFY BOUNDS The starting point is choosen to satisfy all the simple bounds on nonlinear variables. If this starting point is employed, then more care than usual should employed when choosing the bounds on the nonlinear variables. In particular very tight bounds should be avoided. Default value: MSK STARTING POINT FREE 9.2.38 MSK IPAR LIC TRH EXPIRY WRN Corresponding constant: MSK IPAR LIC TRH EXPIRY WRN Description: If a license feature expires in a numbers days less than the value of this parameter then a warning will be issued. Possible Values: Any number between 0 and +inf. Default value: 7
