Description Vasco Alves 2013-10-12 10:48:46 UTC
I think the NLP Solver really needs to be ported to native code. It reduces Java code, which seems to be a sort of mid-term goal for LO. It also performs some of the most performance intensive operations in the whole of LO, so it seems we'd wand this to run closer to the metal. 

Microsoft Excel of course has non-linear algorithms fully integrated. 

PS - I wasn't sure whether to submit this to Spreadsheet or Extensions. Please move it if it's not in the correct section.

Are there any performance measurements about NLPSolver efficiency?

I am not sure that rewriting from Java to C++ will provide dramatically speed-up.
