doudizhu_learning_environment is a research platform for a game named doudizhu (aka fighting the landlord) (wiki).

The library is written in C++. You can use Cmake to compile and run examples.

The moves in this library are encoded identically with RLCard.

The main usage of the library is very similar with hanabi_learning_environment and bridge_learning_environment.

Installation

You need to have CMake as well as python to install the library.

mkdir build && cd build
cmake ..
make -j10

If you are using python in a specific environment created by programs like Anaconda, you should specify your python executable path

cmake .. -DPython_EXECUTABLE=/path/to/python_executable

The library can also be used by other programs using cmake add_subdirectory() syntax.

Todo:

• Doudizhu observation encoders(Douzero style).
• Gym-like rl envs.
• Doudizhu game examples.
• Add a function to create moves from string.
• Add a function to get move uid from move.
• Add a program to allow human play with random agent through console.
