LightZero is a lightweight, efficient, and easy-to-understand open-source algorithm toolkit that combines Monte Carlo Tree Search (MCTS) and Deep Reinforcement Learning (RL). For any questions about LightZero, you can consult the RAG-based Q&A assistant: ZeroPal.
The integration of Monte Carlo Tree Search and Deep Reinforcement Learning,
exemplified by AlphaZero and MuZero,
has achieved unprecedented performance levels in various games, including Go and Atari.
This advanced methodology has also made significant strides in scientific domains like protein structure prediction and the search for matrix multiplication algorithms.
The following is an overview of the historical evolution of the Monte Carlo Tree Search algorithm series:
LightZero is an open-source algorithm toolkit that combines Monte Carlo Tree Search (MCTS) and Reinforcement Learning (RL) for PyTorch. It supports a range of MCTS-based RL algorithms and applications, offering several key advantages:
- Lightweight.
- Efficient.
- Easy-to-understand.
For further details, please refer to Features, Framework Structure and Integrated Algorithms.
LightZero aims to promote the standardization of the MCTS+RL algorithm family to accelerate related research and applications. A performance comparison of all implemented algorithms under a unified framework is presented in the Benchmark.
- LightZero
Lightweight: LightZero integrates multiple MCTS algorithm families and can solve decision-making problems with various attributes in a lightweight framework. The algorithms and environments LightZero implemented can be found here.
Efficient: LightZero uses mixed heterogeneous computing programming to improve computational efficiency for the most time-consuming part of MCTS algorithms.
Easy-to-understand: LightZero provides detailed documentation and algorithm framework diagrams for all integrated algorithms to help users understand the algorithm's core and compare the differences and similarities between algorithms under the same paradigm. LightZero also provides function call graphs and network structure diagrams for algorithm code implementation, making it easier for users to locate critical code. All the documentation can be found here.
The above picture is the framework pipeline of LightZero. We briefly introduce the three core modules below:
Model:
Model is used to define the network structure, including the __init__ function for initializing the network structure and the forward function for computing the network's forward propagation.
Policy:
Policy defines the way the network is updated and interacts with the environment, including three processes: the learning process, the collecting process, and the evaluation process.
MCTS:
MCTS defines the structure of the Monte Carlo search tree and the way it interacts with the Policy. The implementation of MCTS includes two languages: Python and C++, implemented in ptree and ctree, respectively.
For the file structure of LightZero, please refer to lightzero_file_structure.
LightZero is a library with a PyTorch implementation of MCTS algorithms (sometimes combined with cython and cpp), including:
The environments and algorithms currently supported by LightZero are shown in the table below:

You can install the latest LightZero in development from the GitHub source codes with the following command:
git clone https://github.com/opendilab/LightZero.git
cd LightZero
pip3 install -e .Kindly note that LightZero currently supports compilation only on Linux and macOS platforms.
We are actively working towards extending this support to the Windows platform.
Your patience during this transition is greatly appreciated.
We also provide a Dockerfile that sets up an environment with all dependencies needed to run the LightZero library. This Docker image is based on Ubuntu 20.04 and installs Python 3.8, along with other necessary tools and libraries. Here's how to use our Dockerfile to build a Docker image, run a container from this image, and execute LightZero code inside the container.
- Download the Dockerfile: The Dockerfile is located in the root directory of the LightZero repository. Download this file to your local machine.
- Prepare the build context: Create a new empty directory on your local machine, move the Dockerfile into this directory, and navigate into this directory. This step helps to avoid sending unnecessary files to the Docker daemon during the build process.
mkdir lightzero-docker mv Dockerfile lightzero-docker/ cd lightzero-docker/ - Build the Docker image: Use the following command to build the Docker image. This command should be run from inside the directory that contains the Dockerfile.
docker build -t ubuntu-py38-lz:latest -f ./Dockerfile . - Run a container from the image: Use the following command to start a container from the image in interactive mode with a Bash shell.
docker run -dit --rm ubuntu-py38-lz:latest /bin/bash
- Execute LightZero code inside the container: Once you're inside the container, you can run the example Python script with the following command:
python ./LightZero/zoo/classic_control/cartpole/config/cartpole_muzero_config.py
Train a MuZero agent to play CartPole:
cd LightZero
python3 -u zoo/classic_control/cartpole/config/cartpole_muzero_config.pyTrain a MuZero agent to play Pong:
cd LightZero
python3 -u zoo/atari/config/atari_muzero_config.pyTrain a MuZero agent to play TicTacToe:
cd LightZero
python3 -u zoo/board_games/tictactoe/config/tictactoe_muzero_bot_mode_config.pyTrain a UniZero agent to play Pong:
cd LightZero
python3 -u zoo/atari/config/atari_unizero_config.pyThe LightZero documentation can be found here. It contains tutorials and the API reference.

- Below are the benchmark results of AlphaZero and MuZero on three board games: TicTacToe, Connect4, Gomoku.
- Below are the benchmark results of MuZero, MuZero w/ SSL , EfficientZero and Sampled EfficientZero on three discrete action space games in Atari.
- Below are the benchmark results of Sampled EfficientZero with
Factored/Gaussianpolicy representation on three classic continuous action space games: Pendulum-v1, LunarLanderContinuous-v2, BipedalWalker-v3 and two MuJoCo continuous action space games: Hopper-v3, Walker2d-v3.
"Factored Policy" indicates that the agent learns a policy network that outputs a categorical distribution. After manual discretization, the dimensions of the action space for the five environments are 11, 49 (7^2), 256 (4^4), 64 (4^3), and 4096 (4^6), respectively. On the other hand, "Gaussian Policy" refers to the agent learning a policy network that directly outputs parameters (mu and sigma) for a Gaussian distribution.
- Below are the benchmark results of GumbelMuZero and MuZero (under different simulation cost) on four environments: PongNoFrameskip-v4, MsPacmanNoFrameskip-v4, Gomoku, and LunarLanderContinuous-v2.
