418 APPENDIX B. PARAMETERS B.1.43 dparam.mio max time Corresponding constant: dparam.mio max time Description: This parameter limits the maximum time spent by the mixed-integer optimizer. number means infinity. A negative Possible Values: Any number between -inf and +inf. Default value: -1.0 B.1.44 dparam.mio max time aprx opt Corresponding constant: dparam.mio max time aprx opt Description: Number of seconds spent by the mixed-integer optimizer before the dparam.mio tol rel relax int is applied. Possible Values: Any number between 0.0 and +inf. Default value: 60 B.1.45 dparam.mio near tol abs gap Corresponding constant: dparam.mio near tol abs gap Description: Relaxed absolute optimality tolerance employed by the mixed-integer optimizer. This termination criteria is delayed. See dparam.mio disable term time for details. Possible Values: Any number between 0.0 and +inf. Default value: 0.0

B.1. DPARAM: DOUBLE PARAMETERS 419 See also: • dparam.mio disable term time Certain termination criteria is disabled within the mixedinteger optimizer for period time specified by the parameter. B.1.46 dparam.mio near tol rel gap Corresponding constant: dparam.mio near tol rel gap Description: The mixed-integer optimizer is terminated when this tolerance is satisfied. criteria is delayed. See dparam.mio disable term time for details. This termination Possible Values: Any number between 0.0 and +inf. Default value: 1.0e-3 See also: • dparam.mio disable term time Certain termination criteria is disabled within the mixedinteger optimizer for period time specified by the parameter. B.1.47 dparam.mio rel add cut limited Corresponding constant: dparam.mio rel add cut limited Description: Controls how many cuts the mixed-integer optimizer is allowed to add to the problem. Let α be the value of this parameter and m the number constraints, then mixed-integer optimizer is allowed to αm cuts. Possible Values: Any number between 0.0 and 2.0. Default value: 0.75
