Method Detail

toText

public abstract java.lang.String toText()

Returns a string representation of this program. (Instead of toString - Used by Javolution)

Returns:

number of function nodes

getName

public abstract java.lang.String getName()

Returns the name of this program.

Returns:

name of this program

eval

public abstract java.lang.Object eval(java.lang.Object fitnessCase)

Returns evaluation of this program with the given parameter

Parameters:

fitnessCase - fitness case to evaluate

Returns:

evaluation result

countNodes

public abstract int countNodes()

Returns the number of nodes this program has.

Returns:

number of children nodes

countProgramNodes

public abstract int countProgramNodes()

Returns the number of program nodes this program has. This method traverses all the children nodes recursively until the leaf nodes are reached and counts the number of programs.

Returns:

number of program nodes

countFunctionNodes

public abstract int countFunctionNodes()

Returns the number of function nodes this program has. This method traverses all the children nodes recursively until the leaf nodes are reached and counts the number of functions.

Returns:

number of function nodes

clone

public abstract java.lang.Object clone()

Returns a deep copy of this Program instance

Overrides:

clone in class java.lang.Object

Returns:

deep copy of this program
