Enum PresolveMode
Enum to control presolve modes at the beginning of the solution process.

Syntax
public enum PresolveMode
Fields
Name | Description |
---|---|
DefaultPresolve | Presolve is applied. |
IgnoreInfeasibilities | Presolve applied, but a problem will not be declared infeasible if primal infeasibilities are detected. The problem will be solved by the LP optimization algorithm, returning an infeasible solution, which can sometimes be helpful. |
NoPresolve | Presolve is not applied. |
PresolveAlwaysRemoveRedundantBounds | Presolve is applied, and bounds detected to be redundant are always removed. |
PresolveRetainRedundantBounds | Presolve applied, but redundant bounds are not removed. This can sometimes increase the efficiency of the barrier algorithm. |
