Dear Author:
I also have another question about running speed of ALPAQA. I'm using the python version of the ALPAQA(.build, not .compile)， and I haven‘t tired C++ version. So which is faster, the C++ version 、the python version(.build), or the python version(.compile)? Looking forward to your reply.

Hello,

On Windows, alpaqa requires Microsoft Visual Studio for the compilation of CasADi problems. The C code is compiled by invoking cmake -B build -S /folder/containing/generated/code -A x64 (where the final argument depends on whether you're running a 32-bit or 64-bit version of Python. There is currently no way to use your own CMake generator, but I may decide to add this in the future.

If you install Visual Studio now, you may have to clear the CMake cache first: alpaqa cache clean --cmake (https://kul-optec.github.io/alpaqa/Sphinx/usage/tips-and-tricks.html#compilation-and-caching)

In my experience, the Python .compile version is usually 2 to 5 times faster than the Python .build version.
The C++ version of alpaqa allows many different types of problem implementations, so it's hard to say in general how it will compare, it'll depend on your specific implementation.
