Case for a precise-QA-like equilibrium in free boundary, each step in the proximal just gives a bad approximation, files are here: https://drive.google.com/drive/folders/19-F7cVb1yxks42eCI1Nx7DlxjCkyxaaf?usp=drive_link
@dpanici check thru notebooks and link here along with current commit that it occurs at
Right now we still have cases where the proximal optimizer keeps trying smaller and smaller steps until eventually it quits saying
Warning: A bad approximation caused failure to predict improvement.
This seems to be due to inconsistent linearizations or a possibly instability, where small changes in the boundary (the
x
variable the optimizer sees) lead to large changes in the volume (thef
values the optimizer sees).Some possible ideas to make this better:
