[FlagsAttribute] public enum MipPresolve
| Member name | Value | Description | |
|---|---|---|---|
| ReducedCostFixing | 1 | Primal reductions will be performed at each node. Uses constraints of the node to tighten the range of variables, often resulting in fixing their values. This greatly simplifies the problem and may even determine optimality or infeasibility of the node before the simplex method commences. | |
| LogicPreprossessing | 2 | [Unused] This bit is no longer used to control probing. Refer to the integer control PREPROBING for setting probing level during presolve. | |
| AllowChangeBounds | 8 | Allow that symmetry is used to presolve the node problem. | |
| DualReductions | 16 | ||
