470 APPENDIX B. PARAMETERS B.2.112 iparam.param read ign error Corresponding constant: iparam.param read ign error Description: If turned on, then errors in paramter settings is ignored. Possible values: • onoffkey.off Switch the option off. • onoffkey.on Switch the option on. Default value: onoffkey.off B.2.113 iparam.presolve elim fill Corresponding constant: iparam.presolve elim fill Description: Controls the maximum amount of fill-in that can be created during the elimination phase of the presolve. This parameter times (numcon+numvar) denotes the amount of fill-in. Possible Values: Any number between 0 and +inf. Default value: 1 B.2.114 iparam.presolve eliminator max num tries Corresponding constant: iparam.presolve eliminator max num tries Description: Control the maximum number of times the eliminator is tried. Possible Values: A negative value implies MOSEK decides maximum number of times. Default value: -1

B.2. IPARAM: INTEGER PARAMETERS 471 B.2.115 iparam.presolve eliminator use Corresponding constant: iparam.presolve eliminator use Description: Controls whether free or implied free variables are eliminated from the problem. Possible values: • onoffkey.off Switch the option off. • onoffkey.on Switch the option on. Default value: onoffkey.on B.2.116 iparam.presolve level Corresponding constant: iparam.presolve level Description: Currently not used. Possible Values: Any number between -inf and +inf. Default value: -1 B.2.117 iparam.presolve lindep abs work trh Corresponding constant: iparam.presolve lindep abs work trh Description: The linear dependency check is potentially computationally expensive. Possible Values: Any number between 0 and +inf. Default value: 100
