# Play **BreakoutNoFrameskip-v4** with **MuZero** Policy
## Model Description
<!-- Provide a longer summary of what this model is. -->
This implementation applies **MuZero** to the OpenAI/Gym/Atari **BreakoutNoFrameskip-v4** environment using [LightZero](https://github.com/opendilab/LightZero) and [DI-engine](https://github.com/opendilab/di-engine).
**LightZero** is an efficient, easy-to-understand open-source toolkit that merges Monte Carlo Tree Search (MCTS) with Deep Reinforcement Learning (RL), simplifying their integration for developers and researchers. More details are in paper [LightZero: A Unified Benchmark for Monte Carlo Tree Search in General Sequential Decision Scenarios](https://huggingface.co/papers/2310.08348).
