Diamond cutting – any other industries using optimization software?

Question

Recently, I've dived into the rabbit hole of diamond cutting videos on Youtube. Turns out there are a bunch of companies (e.g. sarine - btw, an eyebrow-raising name if there ever was one) making hardware and software for the industry with rather advanced optimization algorithms.What are other niche verticals where optimization software is in widespread use? (Crude refineries aren't niche, and as far as I know, they are fond of linear programming)

I work in semiconductor manufacturing which is basically a giant inverse problem (technically IMHO everything is). I personally work on optimization software which finds the best setting for 7 out of a few hundred settings (collection of settings is called a recipe). We used to use a semi brute force approach and then moved to GA. Currently research is ongoing about mixed integer surrogate models.The Apps market for this industry is huge. The Apps department of one of the biggest equipment manufacturers itself, if counted separately, is in top 10 biggest companies in semiconductor equipment companies.

Logistics.Lots of research papers I noticed from Chinese universities about a decade ago on how to best package given dimensions and with constraints like what material cannot be packaged alongside what, into containers of given sizes.

Aerospace - a company I worked for used a simulated annealing variant to optimise aircraft placement and scheduling according to a rule engine for a series of airports.
