        # 🏆 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.

        🤖 You want to try to train your agents? <a href="http://eepurl.com/ic5ZUD" target="_blank">Sign up to the Hugging Face free Deep Reinforcement Learning Course 🤗 </a>.
