    1212        You can perform basic operations like mutation, crossover, and evaluation of genotypes.
    1313        This way you can perform evolution controlled by python, access and manipulate genotypes.
     14        You can even design and use in evolution your own genetic representation implemented entirely in python.
    1415
    1516        You need to provide one or two parameters when you run this class: the path to Framsticks CLI
