Taiwan |
- Developers: People in many universities, including Université Paris-Sud (France), Maastricht University (Netherlands), National University of Tainan (Taiwan), and National Dong Hwa University (Taiwan).
- Algorithmic Principles: Monte-Carlo Tree Search with RAVE, sequence like simulations, learnt patterns in the tree part.
- Features: Opening book is based on Meta-MCTS, it is the first program to defeat pros on 9x9 board and on 19x19 board, and it is the first program to defeat a top pro with difficult side on 9x9.

Many Faces of Go |
USA |
- Developers: David Fotland and Smart
Games.
- Algorithmic Principles: Mote Carlo
Tree Search with many of the popular
extensions, including RAVE, Silver’s
Beta formula, progressive unpruning,
dynamic komi, and machine optimization
of 3x3 patterns.
- Features: The move generator of the
traditional Go program is used to bias
the tree part of the search. There is no
tree data structure. All search data are
kept in a set of per-core hash tables.

Zen |
Japan |
- Developers: Yoji Ojima (independent
programmer) and Hideki Kato (AI
researcher).
- Algorithmic Principles: MCTS with
hash-coded large-patterns of expert
knowledge of the game of Go and very
smart, sequence-like simulations.
Dynamic-komi and network parallelism are
also used.
- Features: A carefully tuned
combination of significantly improved
sequence-like simulations and the
large-patterns of Go knowledge. The
network parallel algorithm is also our
original

Coldmilk |
Taiwan |
- Developers: Cheng-Wei Chou (National Dong Hwa University, Taiwan) and Shi-Jim Yen (National Dong Hwa University, Taiwan).
- Algorithmic Principles: Coldmilk uses Monte Carlo Tree Search based with RAVE and dynamic komi.
- Features: Coldmilk was developed for small Go board. It is not so strong for 19x19. 9x9 opening book is constructed by the volunteer computing system of a National Science Council research project (99-2221-E-259-009-MY3) in Taiwan.
