Method code available at https://github.com/Eomys/pyleecan/tree/master/pyleecan/Methods/Optimization/OptiGenAlg

class OptiGenAlg(selector=None, crossover=None, mutator=None, p_cross=0.9, p_mutate=0.1, size_pop=40, nb_gen=100, problem=-1, xoutput=-1, logger_name='Pyleecan.OptiSolver', is_keep_all_output=False, init_dict=None, init_str=None)

Bases: pyleecan.Classes.OptiSolver.OptiSolver

Genetic algorithm class

VERSION = 1

save(save_path='', is_folder=False)

Save the object to the save_path

Parameters

• self – A pyleecan object

• save_path (str) – path to the folder to save the object

• is_folder (bool) – to split the object in different files: separate simulation machine and materials

copy(**kwargs)

Return a copy of the class

get_logger()

Get the object logger or its parent’s one

Parameters

obj – A pyleecan object

Returns

logger – Pyleecan object dedicated logger

Return type

logging.Logger

compare(other, name='self')

Compare two objects and return list of differences

as_dict(**kwargs)

Convert this object in a json serializable dict (can be use in __init__). Optional keyword input parameter is for internal use only and may prevent json serializability.
