The other camp — the theory camp — has pursued sample-efficient alternatives (model-based RL, offline RL, model-predictive control) that have not achieved PPO's adoption because they require more domain knowledge and more careful tuning. PPO's historical position is therefore ambivalent. It is the last widely adopted RL algorithm that was designed for generality rather than for a specific domain or scale regime. It solved the problem of stable poli...
