13.4. Agents¶

Next we need agents. Here’s the class definition:

class Agent:

    def __init__(self, loc, fit_land):
        self.loc = loc
        self.fit_land = fit_land
        self.fitness = fit_land.fitness(self.loc)

    def copy(self):
        return Agent(self.loc, self.fit_land)

The attributes of an Agent are:

loc: The location of the Agent in the fitness landscape.
fit_land: A reference to a FitnessLandscape object.
fitness: The fitness of this Agent in the FitnessLandscape, represented as a number between 0 and 1.

Agent provides copy, which copies the genotype exactly. Later, we will see a version that copies with mutation, but mutation is not necessary for evolution.
