individual module

This module defines the Individual class.

This module defines the Individual class, used to create inidividuals. It defines the methods allowed on individuals, including the mutations and evaluation of individuals.

class individual.Individual(individual_genotype: Dict[str, Tuple[type, List[Union[int, float]]]], constraint: str = 'Soft')

Bases: object

The Individual class, used to define the individuals of a population.

Defines an individual in a population, performs the mutations and evaluations of individuals.

copy() → individual.Individual

Returns a deepcopy of the individual.

display() → str

Returns the individual’s genotype in a readable fstring.

evaluate(optimization_func: Callable = <function Individual.<lambda>>, fitness: Callable = <function Individual.<lambda>>) → Union[int, float]

Evaluates the performance of an individual on the task to optimize.

Parameters

• optimization_func (Callable) – The problem to optimize. This can be

• defined or can be one of the test functions. (manually) –

• fitness (Callable) – The fitness function to use to optimize the task. For example, this can be a minimization problem (fitness=minimize). This can be manually defined or can be one of the test functions.

Returns

The individual’s score on the optimization task.

Return type

score (float)

mutate() → None

Mutates the entire individual.
