Matilda - Go/Igo/Wéiqí/Baduk playing software

Matilda is a competitive computer Go playing engine and accompanying software. Go is an ancient and beautiful strategy board game; you can read more about it here.

Implementation-wise Matilda is a MCTS Mogo-like program. It is aimed at 64 bit computers in shared memory, playing with Chinese rules via the Go Text Protocol. It is versatile and optimized for speed in a lot of areas, though some changes require a recompilation.

The relative strength of Matilda can be seen from playing on the CGOS. It is currently much stronger in smaller boards than in larger ones.

System Requirements

• Linux, BSD, macOS or other POSIX 2004 compliant system
• C99 compiler suite with support for OpenMP 3.0 (like GCC or clang)

Before using read the INSTALL file carefully, and at least modify the file src/inc/config.h to your taste.

How to

You can play with Matilda out of the box using a text interface. For a graphical interface you can connect it with any GTP-speaking program that supports Chinese rules, like GoGui. Matilda also includes matilda-twogtp for self-play and benchmarking.
