Use the evolution control bar that directly sets the evolution speed of the model.
Touch the bar within the positive half (∞) in order to evolve the model
seeking for characteristics you like. If you don't like a change then
simply touch the bar within the negative half (○) so the application
involves the model undoing the evolution history. The next
time you evolve the model the tool will generate a different
evolutionary path. Sometimes you have to pass through configurations you don't like to reach one you like.
Playing this game of evolution-involution teaches the internal AI engine
of the application how to better generate new evolutionary paths for
accelerating the convergence. Convergence is reached when the user is
satisfied with the model configuration and no more evolution is
necessary.
