The goal is to implement the code into pfs_utils so it can be used on the fly in future runs. </p> PIPE2D-954

Incorporate black dot optimization algorithm in pfs_utils

I just got the theta-crossing design and will try to generate phi-cross and theta-cross data for you to test. </p> <p>Pushed the version of the algorithm for a reveiw. The algorithm takes mcs data and original dot positions as an input and gives penalty scores for modified dots' positions. The penalty is calculated as: a number of points seen in the data, although they should be covered, given the dot position + number of points not seen in the data, although they should not be covered given the dot position. The `optimize_function` can be passed to a minimizer to find the best solution for new positions. <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=chyan" class="user-hover" rel="chyan">chyan</a> I added you for a review, just in case if you notice some glaring inconsistencies, but I expect main input from Paul and Hassan.</p> <p>Reviewed pull request <a href="https://github.com/Subaru-PFS/pfs_utils/pull/44" class="external-link" rel="nofollow">https://github.com/Subaru-PFS/pfs_utils/pull/44</a> . Mainly editorial comments added.</p> <p>Merged after comments by Hassan and Paul. The biggest improvement was the vectorization of the computation, so the algorithm now finishes in 5 seconds or so.</p> Relates PIPE2D-970 PIPE2D-997 PIPE2D-1048 Development Rank 0|zzsh26:zy Reviewers hassan Sprint 2DDRP-2021 A12 2DDRP-2022 A Story Points 2.0
