Calc solvers - what to say in the Calc Guide

hmm - there are bits and pieces here and there.

For example the first two choices (DEPS & SCO) have some explanation over
at AOO wiki
If that is still relevant for LibreOffice I can't say, but likely.
CoinMD (which I assume here is type of Coin-MP) has a lot of generalized
references, even a wiki page with a paragraph or two that might be worth
drafting for service here:

anyway - I'm just using DDG to search for info on the different solver
types, and you get the idea.

There is a couple of examples of tutorials the reference solvers in Calc
(one of which actually uses the same example data to show how to solve both
in Excel and Calc), but the couple I reviewed only use one as an example.

I did find one for Excel that has an over view which I thought was a decent
balance of information on the three solver models available there at:

IDK if any of the helps, hope it does.

Best wishes,
