public enum RefineOps
Members
Member name Value Description
LPOptimal 1 Run the solution refiner on an optimal solution of a continuous problem.
MIPSolution 2 Run the solution refiner when a new solution is found during a tree search. The refiner will be applied to the presolved solution before any post-solve operations are applied.
LP 8 Run the solution refiner on each node of the MIP search.
LPPresolve 16 Run the solution refiner on an optimal solution before postsolve on a continuous problem.
IterativeRefiner 32 Apply the iterative refiner to refine the solution.
RefinerPrecision 64 Use higher precision in the iterative refinement.
RefinerUsePrimal 128 If set, the iterative refiner will use the primal simplex algorithm.
RefinerUseDual 256 If set, the iterative refiner will use the dual simplex algorithm.
MIPfixglobals 512 Refine MIP solutions such that rounding them keeps the problem feasible when reoptimized.
MIPfixglobalstarget 1,024 Attempt to refine MIP solutions such that rounding them keeps the problem feasible when reoptimized, but accept integers solutions even if refinement fails.
