ZeroObjNodes

Zero-objective heuristic

Type: int
Default value: 0
Minimum value: 0
Maximum value: Infinity

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
