Class Fibonacci

java.lang.Object
  org.jgap.gp.GPProblem
      examples.gp.Fibonacci

public class Fibonacci
extends GPProblem

Example demonstrating Genetic Programming (GP) capabilities of JGAP.

Here, the Fibonacci sequence is calculated (only integers are used).

Please note: We try to find a program that computes Fibonacci iteratively.

This example utilizes a INodeValidator (see FibonacciNodeValidator).

Each new best solution found will be displayed as a graphical tree representing the GP. The tree is written to a PNG-imagefile onto harddisk.
