All Implemented Interfaces:

java.lang.Comparable<Objective>

public class Objective
extends java.lang.Object
implements java.lang.Comparable<Objective>

The Objective is the identifier for a single objective in the Objectives. It is specified by the following properties:

• Name
• Minimization or Maximization

Each Evaluator sets a specific amount of Objective-Value pairs. Moreover, each Evaluator has to set the same Objectives for all phenotypes.
