MIP Heuristic

Type : Selection

Range : The settings listed below

Default : Automatic

This option specifies which MIP heuristic search approach to apply to try to find an initial integer feasible point. Possible values are:

  • Automatic

  • None

  • Not used

  • Feasibility pump

  • MPEC

  • Diving

Setting ‘None’ disables heuristic search. Setting ‘MPEC’ implies that the heuristic is applied based on the MPEC formulation.

If a heuristic search procedure is enabled, the maximum number of iterations before starting the branch and bound procedure is specified by the option MIP Heuristic Iteration Limit .

Note: This option has been deprecated since Knitro version 12.4. As alternatives, you can use MIP Heuristic Diving , MIP Heuristic Feasibility Pump , MIP Heuristic MPEC , and MIP Heuristic Strategy .
