Efficient Frontier Constraint Editing

Applies to:

• Evolver 7.x and Up

• @RISK 7.x and Up, Industrial Edition

Question:
When I select Efficient Frontier and try to edit my constraints, I can select an "=" constraint, but the software changes it. Why?

Answer:
This behavior is due to a limitation of the underlying OptQuest engine:

• You can have an "=" constraint, but you cannot set an "=" constraint for a specific value or list of values.

• Efficient Frontier analysis runs only in OptQuest, not the Genetic Algorithm.

Note:

• This limitation applies only to the Efficient Frontier analysis type.

• For the Standard analysis type, all five constraint types, including "=" and ">", are available in both OptQuest and the Genetic Algorithm.
