The computer industry has advanced so much to have such tools to solve linear programming problems.
The real task is setting up the data in the first place.
There were no tools when I wrote my first one for animal feeds. I read the math book and then constructed the programs on a machine that I had never seen, with 0.000000064 gig of memory, using a language I never heard of.
I designed a relational database before that was a term and wrote my own memory swapping routines. It increased the company’s share of the market by 20% (not of what they had, but the entire market). Unfortunately, I never published anything.
It ran for 18 years without a single program change.
Good article to get people to think about that type of solution.
