Quick recap for the folks on the list:
Currently the LibreOffice wiki includes under the FAQs section a

Drew,
Many thanks for your efforts in trying to get to the bottom of this.
I think that putting the information on the wiki is a good idea. The
relevant chapter of the Calc Guide (Chapter 9, Data Analysis) is already
very thick and would not benefit from being expanded further to include

HI,
Well, I noticed something aside from the Guide and that is the FAQ
over on the wiki.

Now, it turns out that the French version of that FAQ points to a page
(first link on the page) on the TDF wiki but none of the other
languages do. They poin

Kohei and Drew,
Many thanks for getting back to me on this topic.
For the 6.4 update to the Calc Guide, I will follow Kohei's advice that it
is probably beyond the scope of the document to provide guidance on how to
select a solver.
I'll try to make some time before the 7.0 Calc Guide update to

This is strictly my personal opinion.
Which optimization solver to pick really depends on the characteristics

All,
Can anybody advise me please?
In 6.4, Calc seems to offer a choice of five different solvers, these are:
- DEPS Evolutionary Algorithm.
- SCO Evolutionary Algorithm.
- LibreOffice CoinMP Linear Solver.
- LibreOffice Linear Solver.
- Libre Office Swarm Non-Liner Solver (exper
