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.
