Implementation of the blocking_qubits parameter in the GroverOptimizer function

1

### What is the expected enhancement? Implement into GroverOptimizer: (https://github.com/Qiskit/qiskitoptimization/blob/main/qiskit_optimization/algorithms/grover_optimizer.py) the code modification to include Blocking_Qubits as input parameter in addition to Blocking_Enable=True in order to perform a distribution/parallelisation of...

### What is the expected enhancement? Please could you add bounds support in qiskit.algorithms.optimizers.SPSA.minimize. https://qiskit.org/documentation/stubs/qiskit.algorithms.optimizers.SPSA.minimize.html#qiskit.algorithms.optimizers.SPSA.minimize For now bounds are ignored. Thank you !

The tutorial of converters needs to explain how solutions are interpreted

7

### What is the expected enhancement? The tutorial of converters explains how we apply `convert` only. But, it is also important how we interpret solutions from the converted problem to...

### What should we add? Support custom mixers and initial states in the ``QAOAClient``. This is also required for #358 since the warm starting requires setting both these attributes. To...

### What should we add? The ``WarmStartQAOAOptimizer`` currently only allows a ``QAOA`` object as input for the QAOA algorithm. It would be great to extend this to also support the...
