Bases: `Protocol`
|
||
|
||
Callable Protocol for minimizer.
|
||
|
||
This interface is based on [SciPy’s optimize module](https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.minimize.html).
|
||
|
||
> 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).
