import tensorwaves.optimizer.minuit

Minuit2 adapter to the iminuit.Minuit package.

class Minuit2(callback: Optional[Callback] = None, use_analytic_gradient: bool = False, minuit_modifier: Optional[Callable[[Minuit], None]] = None)

Bases: Optimizer

Adapter to Minuit2.

Implements the Optimizer interface using iminuit.Minuit.

Parameters

• callback – Optionally insert behavior through callbacks into the optimize() method.

• use_analytic_gradient – Use the Estimator.gradient() when calling optimize().

• minuit_modifier – Modify the internal iminuit.Minuit optimizer that is constructed during the optimize() call. See Minuit2 for an example.

optimize(estimator: Estimator, initial_parameters: Mapping[str, Union[complex, float]]) → FitResult

Execute optimization.
