differential_evolution module

Define DifferentialEvolution.

class DifferentialEvolution(*, compensating_elements, objective_factory, design_space, compute_beam_propagation, cavity_settings_factory, reference_simulation_output, 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[FieldMap])

• objective_factory (ObjectiveFactory)

• design_space (DesignSpace)

• compute_beam_propagation (Callable[[Mapping[FieldMap, CavitySettings]], SimulationOutput])

• cavity_settings_factory (CavitySettingsFactory)

• reference_simulation_output (SimulationOutput)

• 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.

Return type:

OptiSol

Returns:

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

_algorithm_parameters()

Create the kwargs for the optimisation.

Return type:

dict
