Weiqi games as a tree: Zipf's law of openings and beyond

Li-Gong Xu, Ming-Xia Li, Wei-Xing Zhou
2015 Europhysics letters  
Contrary to the western chess, Weiqi games are less studied by academics partially because Weiqi is popular only in East Asia, especially in China, Japan and Korea.  ...  These findings are the same as for chess and support the conjecture that the popularity distribution of board game openings follows the Zipf law with a universal exponent.  ...  We acknowledge financial support from the Fundamental Research Funds for the Central Universities.  ...

FIDE Chess Network

Kristijan Breznik, Vladimir Batagelj
2016 Austrian Journal of Statistics  
This paper analyses all of the rated chess games published on the FIDE website from January 2008 to September 2010 with network analytic methods.  ...  The game of chess has a long and rich history. In the last century it has been closely connected to the world chess federation FIDE1.  ...  To play in open tournaments it is very risky for world class chess players and it is a great potential threat for a loss of their rating points.  ...

Optimal Player Information MCTS applied to Chinese Dark Chess

Nicolas Jouandeau
2015 2015 Conference on Technologies and Applications of Artificial Intelligence (TAAI)  
OPI-MCTS is experimented in Chinese Dark Chess, which is a imperfect information game. OPI-MCTS is compared with classical MCTS.  ...  Alpha-beta and Monte-Carlo Tree Search (MCTS) are two powerful paradigms useful in computer games. When considering imperfect information, the tree that represents the game has to deal with chance.  ...  RELATED WORKS In this section we expose related works on CDC. Recent works on this game concern alpha-beta pruning, MCTS improvements, openings and endgame databases. Winands et al.  ...

Small and Large MCTS Playouts Applied to Chinese Dark Chess Stochastic Game [chapter]

Nicolas Jouandeau, Tristan Cazenave
2014 Communications in Computer and Information Science  
Monte-Carlo tree search is a powerful paradigm for full information games. We present various changes applied to this algorithm to deal with the stochastic game Chinese Dark Chess.  ...  Introduction Chinese Dark Chess (CDC) is a popular stochastic two players game in Asia that is often played on 4x8 rectangular board where players do not know flipping moves' payoff.  ...  The two player (called black and red) start with the same set of pieces: one king, two guards, two bishop, two knights, two rooks, two cannons and five pawns (pieces that are similar to Chinese Chess).  ...

Time Management for Monte-Carlo Tree Search in Go [chapter]

Hendrik Baier, Mark H. M. Winands
2012 Lecture Notes in Computer Science  
While MCTS allows for fine-grained time control, little has been published on time management for MCTS programs under tournament conditions.  ...  The dominant approach for programs playing the game of Go is nowadays Monte-Carlo Tree Search (MCTS).  ...  This work is funded by the Netherlands Organisation for Scientific Research (NWO) in the framework of the project Go4Nature, grant number 612.000.938.  ...

Reverse Engineering, Some Board Games as a Key to the Development of Artificial Intelligence and Construction of Economic Models

Ewa Drabik
2018 Economics World  
Reverse engineering can be applied for the sake of creating artificial intelligence, e.g. when the used methods are based on very old games, such as Go and chess.  ...  A computers' arrival at that level is due to imitation of human Go or chess play. A particular emphasis shall be placed upon the Go game, known for 5,500 years.  ...  algorithms. organizing chess program tournaments.  ...
