Have you seen the various related discussions here on Discourse. For example:

> [@Latest recommendations for global optimization](https://discourse.julialang.org/t/latest-recommendations-for-global-optimization/17718/32):
>
> Yes, with even more conservative tuning, SA also converges for that function, but it’s quite a difficult case, I’ve never encountered anything like that in my “real life” applications.

This discussion also contains a reference to a paper by Guvenen et al. that benchmarks optimizers for a number of problems, including economic models.

Also of interest: the comment here

> [@How to put bounds on Nelder-Mead in Optim?](https://discourse.julialang.org/t/how-to-put-bounds-on-nelder-mead-in-optim/58183/5):
>
> A long, perhaps off-topic discussion could start from here. Among economists doing structural work, N-M is still quite popular. Whether this is a good choice or not, is hard to say. Each problem has its own issues and the question “what is the best algorithm?” probably does not have a good answer (unless it is a problem specific one). One interesting reference for structural economic problems is Arnoud, Antoine, Fatih Guvenen, and Tatjana Kleineberg. 2019. “Benchmarking Global Optimizers.” Wo…

that argues against Nelder Mead for the local.
