[libreoffice-documentation] Fw: Re: LO Calc - Question About Solver Engines

Following a discussion during yesterday's team call, I emailed the developers to see if anybody could shed any light on the relative merits of the two solvers provided in Calc 6.2.

For information, I am forwarding the response from Kohei Yoshida which contains a useful link to a paper comparing various open source linear program solvers (including the two that we provide, lp_solve and CoinMP).

Is it possible for a developer with appropriate knowledge to provide me with some indication of why a user might want to use one engine in preference to the other? Are there circumstances in which one is likely to perform better than the other?

I for one did not do any sort of fair comparisons, but I found the following paper which may help:


You can skip to the conclusions on page 33 to get the summary of their comparisons. CLP == CoinMP as far as I can tell.
