class DifferentialEvolution(*, compensating_elements, elts, objectives, variables, compute_beam_propagation, compute_residuals, cavity_settings_factory, reference_simulation_output, constraints=None, compute_constraints=None, optimisation_algorithm_kwargs=None, history_kwargs=None, **kwargs)

Bases: DownhillSimplex

Differential evolution method, which does not use derivatives.

Warning

This method was not tuned for this problem yet.

Parameters:

• compensating_elements (Collection[Element])

• elts (ListOfElements)

• objectives (Collection[Objective])

• variables (Collection[Variable])

• compute_beam_propagation (Callable[[SetOfCavitySettings], SimulationOutput])

• compute_residuals (Callable[[SimulationOutput], Any])

• cavity_settings_factory (CavitySettingsFactory)

• reference_simulation_output (SimulationOutput)

• constraints (Collection[Constraint] | None, default: None)

• compute_constraints (Callable[[SimulationOutput], ndarray] | None, default: None)

• optimisation_algorithm_kwargs (dict[str, Any] | None, default: None)

• history_kwargs (dict[str, Any] | None, default: None)

supports_constraints: bool = False

optimize()

Set up the optimisation and solve the problem.

Returns:

info – Gives list of solutions, corresponding objective, convergence violation if applicable, etc.

Return type:

OptiSol

_algorithm_parameters()

Create the kwargs for the optimisation.

Return type:

dict
