    00026  *   This is a example implementation for a fitness strategy. It use a     *
    00027  *   other fitness strategy to calculate a value. If the value is lower    *
    00028  *   than 10 it will give value*value back. Else it will be 100.           *
    00029  *   So the most values are by 100 and of one plane. The gen. Alg lose by  *
    00030  *   this strategy his information how to optimize the individual. Because *
    00031  *   all individual are equal good. Only small part of it are better.      *
    00032  *   This is the worst case for a gen. Alg.                                *
