public enum MultiObjOps
| Member name | Value | Description | |
|---|---|---|---|
| Enabled | 1 | XPRS_MULTIOBJOPS_PRESOLVEApply multi-objective modifications during presolve. If this bit is not set, the original problem will be modified when solving each subsequent objective, and these modifications will remain in the problem after the solve has completed. | |
| Presolve | 2 | XPRS_MULTIOBJOPS_RCFIXINGReduced cost fixing. If this bit is set, optimality of earlier objectives will be preserved by fixing all non-basic variables with non-zero reduced costs to their bounds. If not set, optimality of earlier objectives will be preserved by adding constraints to the problem. | |
| RCFixing | 4 |
