MooSuite (ecj 26 API)

java.lang.Object
- ec.Problem

All Implemented Interfaces:

Prototype, Setup, SimpleProblemForm, Serializable, Cloneable
```
public class MooSuite

Several standard Multi-objective benchmarks are implemented:
- ZDT1: Zitzler, Deb & Thiele
- ZDT2: Zitzler, Deb & Thiele
- ZDT3: Zitzler, Deb & Thiele
- ZDT4: Zitzler, Deb & Thiele
- ZDT6: Zitzler, Deb & Thiele
- SPHERE: ftp.tik.ee.ethz.ch/pub/people/zitzler/ZLT2001a.pdf
- SCH: (Schaffer), (a.k.a. F1 in Srinivas & Deb); requires exactly 1 decision variables (genes)
- F2: (Schaffer), (Srinivas & Deb), (Coello Coello & Cortes); requires exactly 1 decision variables (genes)
- unconstrained F3: Schaffer, Srinivas & Deb (Chankong & Haimes); requires exactly 2 decision variables (genes)
- QV: Quagliarella & Vicini
- FON: Fonseca & Fleming (1995); requires exactly 3 decision variables (genes)
- POL: Poloni; requires exactly 2 decision variables (genes)
- KUR: Kursawe from the Errata of Zitzler's TIK-Report 103: "SPEA2: Improving the Strength Pareto Evolutionary Algorithm" (note that many different versions are described in the literature).

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`evaluate(EvolutionState state, Individual ind, int subpopulation, int threadnum)` Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness appropriately.
`void`	`setup(EvolutionState state, Parameter base)` Sets up the object by reading it from the parameters stored in state, built off of the parameter base base.

public void setup(EvolutionState state,

```
    Description copied from interface: Prototype
    
    Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. If an ancestor implements this method, be sure to call super.setup(state,base); before you do anything else.
    For prototypes, setup(...) is typically called once for the prototype instance; cloned instances do not receive the setup(...) call. setup(...) may be called more than once; the only guarantee is that it will get called at least once on an instance or some "parent" object from which it was ultimately cloned.
