Tested in LO 7.2:
The linear solver, CoinMP, and swarm algorithm are available even is a JRE is
not enabled.
the DEPS and SCO algorithms are added when a JRE is enabled.

If you disable the JRE in LibreOffice, a prompt will show to inform that some
algorithms require a JRE. But you can continue anyway. DEPS and SCO algorithms
are unavailable then.

Can't see this note...

I am reluctant to transform the Help into an encyclopaedia. The example in
comment#1 is a great piece of documentation, better fit in the wiki instead. A
link to the wiki in the Help page is OK, as we did in the Calc Functions.

It has been fixed since then.

We used info from the help pages pointed here
