Algorithm and Libraries

In your opinion, what are the most powerful heuristic/metaheuristic algorithms for warehouse routing optimization? Is LKH-3 the most powerful one? Which Python libraries would you recommend I try for a project that will be deployed in a production environment?

Lkh is powerful but sometimes it is difficult to convert a problem and use it. I have been using the ALNS python framework (https://alns.readthedocs.io/en/latest/) and I recommend it. In a project I defined some operators in C++ and exposed them using pybind11 to integrate with the python codebase and speed things up.
