ec.app.twobox

Class TwoBox

java.lang.Object

ec.Problem

ec.gp.GPProblem

ec.app.twobox.TwoBox

All Implemented Interfaces:

Prototype, Setup, SimpleProblemForm, java.io.Serializable, java.lang.Cloneable

public class TwoBox
extends GPProblem
implements SimpleProblemForm

TwoBox implements the TwoBox problem, with or without ADFs, as discussed in Koza-II.

Parameters

base.data classname, inherits or == ec.app.twobox.TwoBoxData	(the class for the prototypical GPData object for the TwoBox problem)
base.size int >= 1	(the size of the training set)
base.range int >= 1	(the range of dimensional values in the training set -- they'll be integers 1...range inclusive)

Parameter bases

base.data

species (the GPData object)

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,

                     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.
