Objectives (Palladio Core)

java.lang.Object
- org.opt4j.core.CriterionSet<Objective>
- - org.opt4j.core.Objectives

All Implemented Interfaces:

Iterable<Map.Entry<Objective,Value<?>>>
```
public class Objectives
extends CriterionSet<Objective>
```
The Objectives contains the Objective-Values pairs of an Individual. Additionally, the feasibility of the Objectives can be set. The feasibility isFeasible() is true by default. Set this value to false to indicate that the corresponding Individual is infeasible (e.g., it violates constraints).
