The Proximal Robust On-Policy Sampling (PROPS) environment builds on the popular Proximal Policy Optimization (PPO) algorithm, a well-regarded RL technique known for its sample efficiency and ability to handle various action spaces. PPO’s success lies in its use of parallel environments, which accelerate training while maintaining stability across different types of tasks. It offers a great balance between speed and performance, making it an ideal choice for problems like those in MuJoCo, which involve continuous action spaces. The PROPS extension further enhances PPO by introducing more robust on-policy sampling, improving stability and overall training efficiency.

PROPS incorporates key insights from PPO, making it well-suited for real-world applications and tasks requiring high sample efficiency. This implementation enhances the standard PPO with a more robust update mechanism and on-policy sampling techniques. It provides pretrained expert policies for six MuJoCo tasks, enabling users to benchmark their models against well-established baselines.
