436 APPENDIX B. PARAMETERS B.2.24 iparam.intpnt basis Corresponding constant: iparam.intpnt basis Description: Controls whether the interior-point optimizer also computes an optimal basis. Possible values: • basindtype.always Basis identification is always performed even if the interior-point optimizer terminates abnormally. • basindtype.if feasible Basis identification is not performed if the interior-point optimizer terminates with a problem status saying that the problem is primal or dual infeasible. • basindtype.never Never do basis identification. • basindtype.no error Basis identification is performed if the interior-point optimizer terminates without an error. • basindtype.reservered Not currently in use. Default value: basindtype.always See also: • iparam.bi ignore max iter Turns on basis identification in case the interior-point optimizer is terminated due to maximum number of iterations. • iparam.bi ignore num error Turns on basis identification in case the interior-point optimizer is terminated due to a numerical problem. B.2.25 iparam.intpnt diff step Corresponding constant: iparam.intpnt diff step Description: Controls whether different step sizes are allowed in the primal and dual space. Possible values: • onoffkey.off Switch the option off. • onoffkey.on Switch the option on. Default value: onoffkey.on
