I have been looking for a C++ library that implements Reinforcement Learning Algorithms but was not very satisfied with the results.
I found the Reinforcement Learning Toolbox 2.0 from the TU Graz but unfortunately, this project is very old and I was unable to get it to compile.
There is also code from Hado van Hasselt. It looks promising but does not seem to be actively maintained.
Which libraries do you use for Reinforcement Learning in C++?
