REFINEOPS

This specifies when the solution refiner should be executed to reduce solution infeasibilities. The refiner will attempt to satisfy the target tolerances for all original linear constraints before presolve or scaling has been applied.

Integer

Bit	Meaning
0	Run the solution refiner on an optimal solution of a non-global problem.
1	Run the solution refiner when a new solution is found during a global search. The refiner will be applied to the presolved solution before any post-solve operations are applied.
2	Run the MIP solution refiner on the final integer solution returned by the optimizer.
3	Run the solution refiner on each node of the MIP search.
4	Run the solution refiner on an optimal solution before postsolve on a non-global problem.

19 (bits 0, 1 and 4 are set)

The MIP refiner option is executed on the final MIP solution returned by any terminated search, including all stopping criteria (e.g. including termination on maxtime with a MIP solution already found).
