ZeroObjNodes
Zero-objective heuristic
| Type: | int |
|---|---|
| Default value: | -1 |
| Minimum value: | -1 |
| Maximum value: | MAXINT |
Number of nodes to explore in the zero objective heuristic. Note that this heuristic is only applied at the end of the MIP root, and only when no other root heuristic finds a feasible solution.
This heuristic is quite expensive, and generally produces poor quality solutions. You should generally only use it if other means, including exploration of the tree with default settings, fail to produce a feasible solution.
Note: Only affects mixed integer programming (MIP) models
For examples of how to query or modify parameter values from our different APIs, refer to our Parameter Examples.
