Since the underlying type is a bigarray, at least mmap should be possible if Bigstringaf would provide a function to create one using an already existing bigarray.

I think I observe the same problem with auglag (global) parameterized by sbplx (local). Optimization stops with NLOPT_FTOL_REACHED while I have called both ```ocaml Nlopt.set_ftol_abs local (-1.0) Nlopt.set_ftol_abs global (-1.0)...
I am using libnlopt-dev version 2.7.1-3build1 on Ubuntu Linux. I wonder if this is a bug affecting several of the optimization algorithms.
By default, those values are all 0s: ``` 15:34:05.32|I: local_ftol_abs before: 0.000000 15:34:05.32|I: local_ftol_rel before: 0.000000 15:34:05.32|I: global_ftol_abs before: 0.000000 15:34:05.32|I: global_ftol_rel before: 0.000000 ``` but the optimization still stops...
I am using the OCaml interface and working on a large unpublished program, the behavior I observe is not easy to replicate/minimize.
What is your complete question?
``` Traceback (most recent call last): File "./bin/fmqa_model.py", line 106, in trained_model = train_regr(x_list, y_list) File "./bin/fmqa_model.py", line 60, in train_regr model = fmqa.FMBQM.from_data(xs, ys, factorization_size = 8) File "/home/berenger/.local/lib/python3.8/site-packages/fmqa-0.0.1-py3.8.egg/fmqa/fm_binary_quadratic_model.py",...
it looks like an hyper parameter users should be allowed to optimize...
there is some WIP here: https://github.com/UnixJunkie/fmqa/tree/driver_cli_program
