490 APPENDIX B. PARAMETERS B.2.164 iparam.sim scaling method Corresponding constant: iparam.sim scaling method Description: Controls how the problem is scaled before a simplex optimizer is used. Possible values: • scalingmethod.free The optimizer chooses the scaling heuristic. • scalingmethod.pow2 Scales only with power of 2 leaving the mantissa untouched. Default value: scalingmethod.pow2 B.2.165 iparam.sim solve form Corresponding constant: iparam.sim solve form Description: Controls whether the primal or the dual problem is solved by the primal-/dual- simplex optimizer. Possible values: • solveform.dual The optimizer should solve the dual problem. • solveform.free The optimizer is free to solve either the primal or the dual problem. • solveform.primal The optimizer should solve the primal problem. Default value: solveform.free B.2.166 iparam.sim stability priority Corresponding constant: iparam.sim stability priority Description: Controls how high priority the numerical stability should be given. Possible Values: Any number between 0 and 100. Default value: 50
B.2. IPARAM: INTEGER PARAMETERS 491 B.2.167 iparam.sim switch optimizer Corresponding constant: iparam.sim switch optimizer Description: The simplex optimizer sometimes chooses to solve the dual problem instead of the primal problem. This implies that if you have chosen to use the dual simplex optimizer and the problem is dualized, then it actually makes sense to use the primal simplex optimizer instead. If this parameter is on and the problem is dualized and furthermore the simplex optimizer is chosen to be the primal (dual) one, then it is switched to the dual (primal). Possible values: • onoffkey.off Switch the option off. • onoffkey.on Switch the option on. Default value: onoffkey.off B.2.168 iparam.sol filter keep basic Corresponding constant: iparam.sol filter keep basic Description: If turned on, then basic and super basic constraints and variables are written to the solution file independent of the filter setting. Possible values: • onoffkey.off Switch the option off. • onoffkey.on Switch the option on. Default value: onoffkey.off B.2.169 iparam.sol filter keep ranged Corresponding constant: iparam.sol filter keep ranged Description: If turned on, then ranged constraints and variables are written to the solution file independent of the filter setting.
