-
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.
- Parameters:
grammar1 (Grammar) – Grammar of species1
grammar2 (Grammar) – Grammar of species2
function (Callable[[a,b], float]) – Function that returns a score for a battle between one individual of species1 and another of species2
representation1 (Representation) – Representation of species1
representation2 (Representation) – Representation of species2
population1_size (int) – Population size of species1
population2_size (int) – Population size of species2
coevolutions (int) – How many iterations of a pair of evolutions
random (Source) – The random number generator
kwargs1 (dict) – The extra arguments for the GP object of species1
kwargs2 (dict) – The extra arguments for the GP object of species2
