162 CHAPTER 9. PARAMETERS 9.2.118 MSK IPAR PRESOLVE LINDEP REL WORK TRH Corresponding constant: MSK IPAR PRESOLVE LINDEP REL WORK TRH Description: The linear dependency check is potentially computationally expensive. Possible Values: Any number between 0 and +inf. Default value: 100 9.2.119 MSK IPAR PRESOLVE LINDEP USE Corresponding constant: MSK IPAR PRESOLVE LINDEP USE Description: Controls whether the linear constraints are checked for linear dependencies. Possible values: • MSK OFF Switch the option off. • MSK ON Switch the option on. Default value: MSK ON 9.2.120 MSK IPAR PRESOLVE MAX NUM REDUCTIONS Corresponding constant: MSK IPAR PRESOLVE MAX NUM REDUCTIONS Description: Controls the maximum number reductions performed by the presolve. The value of the parameter is normally only changed in connection with debugging. A negative value implies that an infinite number of reductions are allowed. Possible Values: Any number between -inf and +inf. Default value: -1

9.2. MSKIPARAME: INTEGER PARAMETERS 163 9.2.121 MSK IPAR PRESOLVE USE Corresponding constant: MSK IPAR PRESOLVE USE Description: Controls whether the presolve is applied to a problem before it is optimized. Possible values: • MSK PRESOLVE MODE FREE It is decided automatically whether to presolve before the problem is optimized. • MSK PRESOLVE MODE OFF The problem is not presolved before it is optimized. • MSK PRESOLVE MODE ON The problem is presolved before it is optimized. Default value: MSK PRESOLVE MODE FREE 9.2.122 MSK IPAR PRIMAL REPAIR OPTIMIZER Corresponding constant: MSK IPAR PRIMAL REPAIR OPTIMIZER Description: Controls which optimizer that is used to find the optimal repair. Possible values: • MSK OPTIMIZER CONCURRENT The optimizer for nonconvex nonlinear problems. • MSK OPTIMIZER CONIC The optimizer for problems having conic constraints. • MSK OPTIMIZER DUAL SIMPLEX The dual simplex optimizer is used. • MSK OPTIMIZER FREE The optimizer is chosen automatically. • MSK OPTIMIZER FREE SIMPLEX One of the simplex optimizers is used. • MSK OPTIMIZER INTPNT The interior-point optimizer is used. • MSK OPTIMIZER MIXED INT The mixed-integer optimizer. • MSK OPTIMIZER MIXED INT CONIC The mixed-integer optimizer for conic and linear problems. • MSK OPTIMIZER NETWORK PRIMAL SIMPLEX The network primal simplex optimizer is used. It is only applicable to pute network problems. • MSK OPTIMIZER NONCONVEX The optimizer for nonconvex nonlinear problems. • MSK OPTIMIZER PRIMAL DUAL SIMPLEX The primal dual simplex optimizer is used. • MSK OPTIMIZER PRIMAL SIMPLEX The primal simplex optimizer is used. Default value: MSK OPTIMIZER FREE

100<br />

9.2.119 MSK IPAR PRESOLVE LINDEP USE<br />

Corresponding constant:<br />

MSK IPAR PRESOLVE LINDEP USE<br />

Description:<br />

Controls whether the <strong>line</strong>ar constraints are checked for <strong>line</strong>ar dependencies.<br />

Possible values:<br />

• MSK OFF Switch the option off.<br />

• MSK ON Switch the option on.<br />
