458 APPENDIX B. PARAMETERS B.2.82 iparam.mio keep basis Corresponding constant: iparam.mio keep basis Description: Controls whether the integer presolve keeps bases in memory. This speeds on the solution process at cost of bigger memory consumption. Possible values: • onoffkey.off Switch the option off. • onoffkey.on Switch the option on. Default value: onoffkey.on B.2.83 iparam.mio local branch number Corresponding constant: iparam.mio local branch number Description: Controls the size of the local search space when doing local branching. Possible Values: Any number between -inf and +inf. Default value: -1 B.2.84 iparam.mio max num branches Corresponding constant: iparam.mio max num branches Description: Maximum number of branches allowed during the branch and bound search. A negative value means infinite. Possible Values: Any number between -inf and +inf. Default value: -1

B.2. IPARAM: INTEGER PARAMETERS 459 See also: • dparam.mio disable term time Certain termination criteria is disabled within the mixedinteger optimizer for period time specified by the parameter. B.2.85 iparam.mio max num relaxs Corresponding constant: iparam.mio max num relaxs Description: Maximum number of relaxations allowed during the branch and bound search. A negative value means infinite. Possible Values: Any number between -inf and +inf. Default value: -1 See also: • dparam.mio disable term time Certain termination criteria is disabled within the mixedinteger optimizer for period time specified by the parameter. B.2.86 iparam.mio max num solutions Corresponding constant: iparam.mio max num solutions Description: The mixed-integer optimizer can be terminated after a certain number of different feasible solutions has been located. If this parameter has the value n and n is strictly positive, then the mixed-integer optimizer will be terminated when n feasible solutions have been located. Possible Values: Any number between -inf and +inf. Default value: -1 See also: • dparam.mio disable term time Certain termination criteria is disabled within the mixedinteger optimizer for period time specified by the parameter.
