Decreases the number of visible subjects. The speed of the algorithm will be widely increased. In our case, you may launch a search from 8 or 24 biomorphs but the functioning is then special. Note that each size of population is associated to a default mutation rate. Note how high the default values are when the populations are small.
Elitist permits to keep the best subject of each generation.
It's essential, mainly for small populations. The two following radio buttons set the type of computing used. This last case is obviously theoretically forbidden since it is the genotype we are looking for. We nevertheless kept this function for a demonstration purpose. It's once again necessary for small populations.
