    # 🏆 The Deep Reinforcement Learning Course Leaderboard 🏆 

    This is the leaderboard of trained agents during the Deep Reinforcement Learning Course. A free course from beginner to expert.

    This is the Soccer environment leaderboard, use Ctrl+F to find your rank 🏆

    We use an ELO rating to sort the models.
    You **can click on the model's name** to be redirected to its model card which includes documentation.
