• 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; 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).

Parameters

base.type String, one of: zdt1, zdt2, zdt3, zdt4, zdt6, sphere, sch, fon, qv, pol, kur, f1, f2, unconstrained-f3

Method Detail

setup

public void setup(EvolutionState state,
                  Parameter base)

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.

evaluate

public void evaluate(EvolutionState state,
                     Individual ind,
                     int subpopulation,
                     int threadnum)

Description copied from interface: SimpleProblemForm

Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness appropriately.
