gmgm - A modern Janggi AI with a deep residual squeeze-excitation net (SENet) and MCTS

gmgm is a Janggi (Korean chess) AI which supports modern Janggi rules. The author tried to faithfully reproduce the rule from Kakao Janggi which means:

• No draws
• Game ends when the game reaches 200 moves, both player passes, or any player goes less or equal to 10 points.
• No repetitive moves - I faithfully tried to reproduce Kakao's repeat move rules, but there may be some holes due to the rule itself being undocumented.

Weights

There is a weight trained by myself This should be good enough to play against most casual players.

Is there some way to try it on?

I created a website that services gmgm on the cloud.

Compiling

Requirements (mostly copied from leela-zero)

• GCC, Clang or MSVC, any C++14 compiler
• Boost 1.58.x or later, headers and program_options, filesystem and system libraries (libboost-dev, libboost-program-options-dev and libboost-filesystem-dev on Debian/Ubuntu)
• zlib library (zlib1g & zlib1g-dev on Debian/Ubuntu)
• Standard OpenCL C headers (opencl-headers on Debian/Ubuntu, or at https://github.com/KhronosGroup/OpenCL-Headers/tree/master/CL)
• OpenCL ICD loader (ocl-icd-libopencl1 on Debian/Ubuntu, or reference implementation at https://github.com/KhronosGroup/OpenCL-ICD-Loader)
• An OpenCL capable device, preferably a very, very fast GPU, with recent drivers is strongly recommended (OpenCL 1.1 support is enough).

Example of compiling - Ubuntu & similar

# Test for OpenCL support & compatibility
sudo apt install clinfo && clinfo

# Clone github repo
git clone https://github.com/ihavnoid/gmgm
cd gmgm
git submodule update --init --recursive

# Install build depedencies
sudo apt install libboost-dev libboost-program-options-dev libboost-filesystem-dev opencl-headers ocl-icd-libopencl1 ocl-icd-opencl-dev zlib1g-dev

# Use stand alone directory to keep source dir clean
cd src
make

# Download net
curl -O https://drive.google.com/file/d/11LLR74LHmRiKKEMZN-WPm8W6HZx1FnSM/view?usp=sharing

# Run binary.  This will open up a gmgm shell
./gmgm_release

# Load net
loadnet sample_net.txt.gz

Acknowledgements

A lot of other pieces of code (specifically the OpenCL code), makefiles and this markdown file itself originated from leela-zero.
The MCTS search and the game logic itself was written from scratch.

License

The code is released under the GPLv3 or later, except for cl2.hpp, half.hpp and the eigen subdirs, which have specific licenses (compatible with GPLv3) mentioned in those files.

Help needed

• Support for some standard Janggi protocol - unfortunately I have no idea what kind of standard protocol we should support.
