C++ Gym for Reinforcement Learning

C++ version of OpenAI Gym

C++ Gym API is nearly identical to the original OpenAI Gym

C++ programmers can use C++ Gym with existing books, research papers, tutorials and websites using OpenAI Gym to implement Reinforcement Learning algorithms

C++ programmers can use C++ Gym to implement Reinforcement Learning algorithms and gain more experience with the field of Artificial Intelligence and Machine Learning

Classic control reinforcement learning environments: Acrobot, Cartpole, Continuous Mountain Car, Mountain Car and Pendulum

To make it as fast as possible for C++ programmers to get started, C++ Gym is implemented as C++ header files

Deep Reinforcement Learning can be implemented with C++ Gym using any available C++ machine learning libraries, including Eigen, PyTorch for C++ and much more

C++ Gym supports C++20 and above
