Exercises

1. Try to increase the value of the node_add_prob parameter and see what happens. Does the algorithm produce any number of hidden nodes, and if so, how many?
2. Try to decrease/increase the compatibility_threshold value. What happens if you set it to 2.0 or 6.0? Can the algorithm find the solution in each case?
3. Try to set the elitism value to zero in the DefaultReproduction section. See what happens. How long did the evolutionary process take to find an acceptable solution in this case?
4. Set the survival_threshold value to 0.5 in the DefaultReproduction section. See how this affects speciation during evolution. Why does it?
5. Increase the additional_num_runs and additional_steps values in order of magnitude to examine further how well the found control strategy is generalized. Is the algorithm still able to find a winning solution?

The last exercise will lead to an increase...
