The Evolution Window
place only within a very narrow band of mutation step size.
The progress window of the Evolution Strategy has a general informative value. One could argue, politically inverted, that revolutionaries find themselves to the right of the evolution window, and ultraconservatives on the left of it. This means regression (rate of progress negativ) for the revolutionaries and stagnation for the ultraconservatives. Finding the proper step size: this is an art, which is of equal importance for politicians, managers and engineers.
