[FlagsAttribute] public enum MultiObjOps
| Member name | Value | Description |
|---|---|---|
| Enabled | 1 | XPRS_MULTIOBJOPS_ENABLED Multi-objective enabled. If this bit is not set, multi-objective problems will treated as single-objective problems, and only objective 0 will be optimized. |
| Presolve | 2 | XPRS_MULTIOBJOPS_PRESOLVE Apply 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. |
| RCFixing | 4 | XPRS_MULTIOBJOPS_RCFIXING Reduced 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. |
| NoSolveAttribs | 8 | XPRS_MULTIOBJOPS_NOSOLVEATTRIBS If this bit is set, the Optimizer will not save the problem attributes after each objective is solved, which reduces memory usage. The attributes will then no longer be queryable via getObjDblAttrib or getObjIntAttrib, which will raise an error. |
