I am not sure how that solves the problem - the issue is the optimizer using the same callback to compute the next point on the curve via gradient or...

> I agree that ideally there would be one clean commit. Great, lets make it so once the dependents are dealt with.

With the primitive based algorithms being the future, that includes a new VQE based on Estimator, where there is no direct state as such in the result, this is no...

> This would be particularly useful in context of the QAOA and VQE runtimes as jobs can get stuck locally This makes it sounds as this happens more frequently than...

It was probably added there since this is the only place that consumes optimizers. It seems very reasonable to me though to have the Minimizer be defined in optimizers. I'll...

The above PR was changed, ahead of merging, so that Minimizer interface is exposed at the [optimizers ](https://qiskit.org/documentation/stubs/qiskit.algorithms.optimizers.html#optimizer-base-class)level

The above does not explicitly call out [extrapolator](https://github.com/Qiskit/qiskit-nature/blob/main/qiskit_nature/algorithms/pes_samplers/extrapolator.py) code that was used for BopesSampler - it is shown in code sample though. Bootstrapping basically took the last solution point as...

From the link this looks like a performance enhancement when using MPS simulator when all qubits are being measured. You can pass in an Aer simulator set for MPS mode...

I guess I am confused - the PR you linked says this as a summary > Performance improvement for the case where all qubits are measured. and later > It...

Do you have a use-case/example of situations where this reverse transformation would be useful for a particular algorithm or problem being solved?
