Class FibonacciNodeValidator

java.lang.Object
  examples.gp.FibonacciNodeValidator

All Implemented Interfaces:

java.io.Serializable, INodeValidator

public class FibonacciNodeValidator
extends java.lang.Object
implements INodeValidator

Validates evolved nodes for the Fibonacci problem. This is mainly to demonstrate how the node validator works.

validate

public boolean validate(ProgramChromosome a_chrom,
                        CommandGene a_node,
                        CommandGene a_rootNode,
                        int a_tries,
                        int a_num,
                        int a_recurseLevel,

                        CommandGene[] a_functionSet,
                        int a_depth,
                        boolean a_grow,
                        int a_childIndex,
                        boolean a_fullProgram)

Validates a_node in the context of a_chrom during evolution. Considers the recursion level (a_recursLevel), the type needed (a_type) for the node, the functions available (a_functionSet) and the depth of the whole chromosome needed (a_depth), and whether grow mode is used (a_grow is true) or not.

Specified by:

validate in interface INodeValidator

Parameters:

a_chrom - the chromosome that will contain the node, if valid (ignored in this implementation)

a_node - the node selected and to be validated

a_rootNode - the root node of a_node, may be null for top nodes

a_tries - number of times the validator has been called, useful for stopping by returning true if the number exceeds a limit

a_num - the chromosome's index in the individual of this chromosome

a_recurseLevel - level of recursion

a_type - the return type of the node needed

a_functionSet - the array of available functions (ignored in this implementation)

a_depth - the needed depth of the program chromosome

a_grow - true: use grow mode, false: use full mode (ignored in this implementation)

a_childIndex - index of the child in the parent node to which it belongs (-1 if node is root node)

a_fullProgram - true: whole program is available in a_chrom

Returns:

true: node is valid; false: node is invalid
