1. Download source code.

    git clone https://github.com/zhangjk95/MahjongAI.git
   

2. Change the working directory to the source code folder.

    cd MahjongAI
   

3. If you are going to play on Majsoul, run

    npm install --prefix ./MajsoulHelper ./MajsoulHelper
   

4. Copy MahjongAI\App.config.example to MahjongAI\App.config and edit it. (Instructions are included in the example.)

5. Open the solution with Visual Studio.

6. Switch the Build Configuration to Release. (The program may be slow in Debug mode and exceed the time limit when making dicisions.)

7. Build and Run!

After the game ends, you can find the replay URLs in MahjongAI\bin\Release\replays.txt.

You can run this program in Docker on either Windows or Linux without ANY requirements other than Docker.

1. Download source code.

    git clone https://github.com/zhangjk95/MahjongAI.git
   

2. Change the working directory to the source code folder.

    cd MahjongAI
   

3. If you are going to play on Majsoul, run

    npm install --prefix ./MajsoulHelper ./MajsoulHelper
   

4. Copy MahjongAI/App.config.example to MahjongAI/App.config and edit it. (Instructions are included in the example.)

    cp MahjongAI/App.config.example MahjongAI/App.config
    $EDITOR MahjongAI/App.config
   

5. Build Docker image.

    ./build.sh
   

6. Run.

     docker run -it mahjong-ai
   

   Note: The replay URLs are stored in /usr/src/app/MahjongAI/bin/Release/replays.txt inside the docker container. If you want to watch replays, You can map a file volume to it in order to save the replays outside the container. Which means, instead of running the command above, you may run the commands below instead:

   touch ~/replays.txt
   docker run -v ~/replays.txt:/usr/src/app/MahjongAI/bin/Release/replays.txt -it mahjong-ai
   

   Then after the game ends, you can find the replay URLs in ~/replays.txt.
