public class GeneFunctionGrow

extends GeneFunction

implements java.lang.Cloneable

A GeneFunctionGrow is a GeneFunction created using the Grow method. In the Grow method, the Gene tree is such that, along any branch, the probability of encountering a Terminal is equal to the probability of encountering a Function.

Constructor Detail

GeneFunctionGrow

public GeneFunctionGrow(int maxDepth,
                        Type type,
                        GPParameters gpParameters,
                        int adfIndex)
                 throws TypeException

Create a Gene tree using the Grow method. The Grow method tries to creates trees in which along any branch, the probability of encountering a Terminal is equal to the probability of enountering a Function.

Parameters:

maxDepth - the maximum depth of the Gene tree to be generated.

type - the required return type of top node in the tree.

gpParameters - the GP parameters for this run.

adfIndex - the index of the ChromosomeParameters to used.

Throws:

TypeException - If a Function or Terminal of a required type could not be found.
