.. py:class:: CooperativeGP(grammar1, grammar2, function, representation1 = None, representation2 = None, population1_size = 100, population2_size = 200, coevolutions = 1000, random = None, kwargs1 = None, kwargs2 = None)

   Bases: :py:obj:`Generic`\ [\ :py:obj:`a`\ , :py:obj:`b`\ ]


   CooperativeGP takes two representations and a function that pits two
   individuals against each other.

   Given grammar1 and grammar 2, a population of each is generated and
   evolved one after the other. The fitness function is the same for
   both evolutions, but first minimizes the function, and the second
   maximizes the fitness. It runs for a given number of iterations
   defined by the coevolutions parameter.

   Creates a new object to co-evolve species1 and species2.
