*4 Tests were run, 0.9 crossover, 0.9 mutation with 0 elitism and 2 elitism, and 1.0 crossover, 1.0 mutation with 0 elitism and 2 elitism.
|
|
\subsection{Fitness Evaluation}
|
|
Fitness is evaluated by taking the absolute value of the predicted y value minus the actual y value.
|
|
If the difference is less than a user provided (default 1.e15) value cutoff it is added to the fitness value. If the difference value is less than the float epsilon value (\~= 0) the number of hits is incremented. Lower fitness values are preferred.

\subsection{Analysis And Conclusion}
|
|
The best average fitness of all the tests was 0.19384 using 0.9 crossover and 0.1 mutation.
