Hi. I am a member of the Documentation Team, currently drafting an updated version of Calc Guide Chapter 9 (Data Analysis) to reflect LO 6.2.

Part of this update is to reflect that there are now two engines available to solve linear programs (lp_solve and CoinMP). The user can switch between engines through a menu on the Options dialog (accessed from the Solver dialog).

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?

Thank you in advance.
