I imagine this is ready since things now pass - you still have WIP in the title.

Today's schedule CI fails due to the error.

I also fixed from qiskit.utils import algorithm_globals used in a qrao test.

Can you fix one other place too - this is a validation function that was used by algos. It will be deprecated/removed from Qiskit and was "moved" to qiskit_algorithms too.

qiskit-optimization/qiskit_optimization/algorithms/recursive_minimum_eigen_optimizer.py

Line 20 in b5b8de8

from qiskit.utils.validation import validate_min

(Simply change from qiskit.utils... to from qiskit_algorithms.utils...

Thanks. I did it.
I also updated the minimum version of scipy to support ScipiMilpOptimizer.

For this

I also updated the minimum version of scipy to support ScipyMilpOptimizer.

the SciPyMilpOptimizer before, and in fact as it still is, is treated as an optional and has conditional logic around that. With bumping the version of scipy that conditional optional logic is not really needed anymore right? Maybe that optional aspect was done more due to the fact that 3.7 was still supported here but SciPy needed 3.8 or above for that version. So bottom line should we get rid of the optional logic there now with this being bumped - its irrelevant after this change.

Thanks. I forgot about optional. I removed it.

Thanks. Could you approve it? I then merge it.

Sorry my bad - the LGTM comment was supposed to have been an Approve!

Thank you for merging it.
