It was marked broken in 1dc27975d1 (May
2025).
But the bug was fixed in October 2025 with:
https://sourceforge.net/p/octave/optim/ci/d8c28ab3f3f37d439bc2d961d79f4a8caa9830d1/
Since there were new commits, but no release. I asked the upstream
maintainer to push the 1.6.3 tag.
I tested it works by importing the library:
nix-shell -p "octave.withPackages (ps: [ ps.optim ])" --run 'octave
--eval "pkg load optim; disp(\"Success!\")"'
