Minimizer

class qiskit.algorithms.optimizers.Minimizer(*args, **kwargs)

Bases: Protocol

Callable Protocol for minimizer.

This interface is based on SciPy’s optimize module.

This protocol defines a callable taking the following parameters:

fun

The objective function to minimize (for example the energy in the case of the VQE).

x0

The initial point for the optimization.

jac

The gradient of the objective function.

bounds

Parameters bounds for the optimization. Note that these might not be supported by all optimizers.

and which returns a minimization result object (either SciPy’s or Qiskit’s).
