Which sources are out there that provide reliable and fast MDP solvers? I prefer that the library is callable from C++ but other languages are fine too.
There is indeed an abundance of repositories on github that at first seem to be appropriate for this task. However, the ones I found so far were either buggy, super slow, or overly optimized for a too specific model (such as all my own implementations).
This question is similar as the question open source LP solvers but now for MDP solvers.
