WebMar 25, 2024 · PPO The Proximal Policy Optimization algorithm combines ideas from A2C (having multiple workers) and TRPO (it uses a trust region to improve the actor). The main idea is that after an update, the new policy should be not too far from the old policy. For that, ppo uses clipping to avoid too large update. Note Webhighway-env - A minimalist environment for decision-making in autonomous driving 292 An episode of one of the environments available in highway-env. In this task, the ego-vehicle is driving on a multilane highway populated with other vehicles. The agent's objective is to reach a high speed while avoiding collisions with neighbouring vehicles.
