Here is a simple working implementation.
>From the beginning of the readme:
Michi --- Minimalistic Go MCTS Engine
Michi aims to be a minimalistic but full-fledged Computer Go program based
on state-of-art methods (Monte Carlo Tree Search) and written in Python.
Our goal is to make it easier for new people to enter the domain of
Computer Go, peek under the hood of a "real" playing engine and be able to
learn by hassle-free experiments - with the algorithms, add heuristics, etc.
The algorithm code size is 540 lines of code (without user interface,
tables and empty lines / comments). Currently, it can often win against
GNUGo on 9×9 on an old i3 notebook, be about even with GNUGo on 15×15 on a
modern higher end computer and about two stones weaker on 19×19 (spending
no more than 30s per move).
This is not meant to be a competitive engine; simplicity and clear code is
preferred over optimization (after all, it's in Python!). But compared to
other minimalistic engines, this one should be able to beat beginner
intermediate human players, and I believe that a *fast* implementation of
exactly the same heuristics would be around 4k KGS or even better.
Michi is distributed under the MIT licence. Now go forth, hack and peruse!
