Project Description:

The main inspiriation for this submission is to focus on improving the optimization scheme. The ansatz and optimization algorithm mimics the one presented in https://arxiv.org/pdf/1903.12166.pdf with only minor adjustment both choosen for its observed resilience and quick convergence. The main deviation, inspired by the work in https://arxiv.org/abs/2102.08403, is to split the ansatz into parameterized blocks which then are individually locally optimized sequentially.

@dylansheils Thank you for your submission. We ran your revised algorithms here and the energy results end up at 0.0, which seems that there are errors somewhere.
