This ist the fist test sketch of our evolutions library. The library provides the data structure of an evolutionary algorithm.
In this example, the EA tries to find the Polygon (toxiclibs Polygon2D) with the best area-to-circumference ratio. It starts with 200 random polygons and calculates 150 generations to find the best solution.
After that you can scroll through the path of the winning polygon by moving the mouse.
The graph shows the best values of every generation (black), the slope this curve (red) and the path of the "winning" polygon (grey)
