ec.app.twobox
Class TwoBox

java.lang.Object
  extended by ec.Problem
      extended by ec.gp.GPProblem
          extended by 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)

clone

public java.lang.Object clone()
Description copied from interface: Prototype
Creates a new individual cloned from a prototype, and suitable to begin use in its own evolutionary context.

Typically this should be a full "deep" clone. However, you may share certain elements with other objects rather than clone hem, depending on the situation:

Implementations.

Specified by:
clone in interface Prototype
Overrides:
clone in class GPProblem

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.

Specified by:
setup in interface Prototype
Specified by:
setup in interface Setup
Overrides:
setup in class GPProblem

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.

Specified by:
evaluate in interface SimpleProblemForm
Overrides:
evaluate in class Problem
