Five divisions, each of eight engines, played two or more ‘DRR’ double round robin phases each, with promotions and relegations following. Classic tempi gradually lengthened and the Premier division’s top two engines played a 100-game match to determine the Grand Champion. The strategy for the selection of mandated openings was finessed from division to division. -
Chess Engine Using Deep Reinforcement Learning Kamil Klosowski
Chess Engine Using Deep Reinforcement Learning Kamil Klosowski 916847 May 2019 Abstract Reinforcement learning is one of the most rapidly developing areas of Artificial Intelligence. The goal of this project is to analyse, implement and try to improve on AlphaZero architecture presented by Google DeepMind team.

PGN/AN Verification for Legal Chess Gameplay
PGN/AN Verification for Legal Chess Gameplay Neil Shah Guru Prashanth [email protected] [email protected] May 10, 2015 Abstract Chess has been widely regarded as one of the world's most popular games through the past several centuries. One of the modern ways in which chess games are recorded for analysis is through the PGN/AN (Portable Game Notation/Algebraic Notation) standard, which enforces a strict set of rules for denoting moves made by each player. In this work, we examine the use of PGN/AN to record and describe moves with the intent of building a system to verify PGN/AN in order to check for validity and legality of chess games. To do so, we formally outline the abstract syntax of PGN/AN movetext and subsequently define denotational state-transition and associated termination semantics of this notation. 1 Introduction Chess is a two-player strategy board game which is played on an eight-by-eight checkered board with 64 squares. There are two players (playing with white and black pieces, respectively), which move in alternating fashion. Each player starts the game with a total of 16 pieces: one king, one queen, two rooks, two knights, two bishops and eight pawns. Each of the pieces moves in a different fashion. The game ends when one player checkmates the opponents' king by placing it under threat of capture, with no defensive moves left playable by the losing player. Games can also end with a player's resignation or mutual stalemate/draw. We examine the particulars of piece movements later in this paper. -

ANALYSIS AND IMPLEMENTATION OF THE GAME ARIMAA Christ-Jan Cox Master Thesis MICC-IKAT 06-05 THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE OF KNOWLEDGE ENGINEERING IN THE FACULTY OF GENERAL SCIENCES OF THE UNIVERSITEIT MAASTRICHT Thesis committee: prof. dr. H.J. van den Herik dr. ir. J.W.H.M. Uiterwijk dr. ir. P.H.M. Spronck dr. ir. H.H.L.M. Donkers Universiteit Maastricht Maastricht ICT Competence Centre Institute for Knowledge and Agent Technology Maastricht, The Netherlands March 2006 II Preface The title of my M.Sc. thesis is Analysis and Implementation of the Game Arimaa. The research was performed at the research institute IKAT (Institute for Knowledge and Agent Technology). The subject of research is the implementation of AI techniques for the rising game Arimaa, a two-player zero-sum board game with perfect information. Arimaa is a challenging game, too complex to be solved with present means. It was developed with the aim of creating a game in which humans can excel, but which is too difficult for computers. I wish to thank various people for helping me to bring this thesis to a good end and to support me during the actual research. First of all, I want to thank my supervisors, Prof. dr. H.J. van den Herik for reading my thesis and commenting on its readability, and my daily advisor dr. ir. J.W.H.M. Uiterwijk, without whom this thesis would not have been reached the current level and the “accompanying” depth. The other committee members are also recognised for their time and effort in reading this thesis. -
Project: Chess Engine 1 Introduction 2 Peachess
P. Thiemann, A. Bieniusa, P. Heidegger Winter term 2010/11 Lecture: Concurrency Theory and Practise Project: Chess engine http://proglang.informatik.uni-freiburg.de/teaching/concurrency/2010ws/ Project: Chess engine 1 Introduction From the Wikipedia article on Chess: Chess is a two-player board game played on a chessboard, a square-checkered board with 64 squares arranged in an eight-by-eight grid. Each player begins the game with sixteen pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. The object of the game is to checkmate the opponent’s king, whereby the king is under immediate attack (in “check”) and there is no way to remove or defend it from attack on the next move. The game’s present form emerged in Europe during the second half of the 15th century, an evolution of an older Indian game, Shatranj. Theoreticians have developed extensive chess strategies and tactics since the game’s inception. Computers have been used for many years to create chess-playing programs, and their abilities and insights have contributed significantly to modern chess theory. One, Deep Blue, was the first machine to beat a reigning World Chess Champion when it defeated Garry Kasparov in 1997. Do not worry if you are not familiar with the rules of chess! You are not asked to change the methods which calculate the moves, nor the internal representation of boards or moves, nor the scoring of boards. 2 Peachess Peachess is a chess engine written in Java. The implementation consists of several components. 2.1 The chess board The chess board representation stores the actual state of the game. -

Move Similarity Analysis in Chess Programs
Move similarity analysis in chess programs D. Dailey, A. Hair, M. Watkins Abstract In June 2011, the International Computer Games Association (ICGA) disqual- ified Vasik Rajlich and his Rybka chess program for plagiarism and breaking their rules on originality in their events from 2006-10. One primary basis for this came from a painstaking code comparison, using the source code of Fruit and the object code of Rybka, which found the selection of evaluation features in the programs to be almost the same, much more than expected by chance. In his brief defense, Rajlich indicated his opinion that move similarity testing was a superior method of detecting misappropriated entries. Later commentary by both Rajlich and his defenders reiterated the same, and indeed the ICGA Rules themselves specify move similarity as an example reason for why the tournament director would have warrant to request a source code examination. We report on data obtained from move-similarity testing. The principal dataset here consists of over 8000 positions and nearly 100 independent engines. We comment on such issues as: the robustness of the methods (upon modifying the experimental conditions), whether strong engines tend to play more similarly than weak ones, and the observed Fruit/Rybka move-similarity data. 1. History and background on derivative programs in computer chess Computer chess has seen a number of derivative programs over the years. One of the first was the incident in the 1989 World Microcomputer Chess Cham- pionship (WMCCC), in which Quickstep was disqualified due to the program being \a copy of the program Mephisto Almeria" in all important areas. -

[Math.HO] 4 Oct 2007 Computer Analysis of the Two Versions
Computer analysis of the two versions of Byzantine chess Anatole Khalfine and Ed Troyan University of Geneva, 24 Rue de General-Dufour, Geneva, GE-1211, Academy for Management of Innovations, 16a Novobasmannaya Street, Moscow, 107078 e-mail: [email protected] July 7, 2021 Abstract Byzantine chess is the variant of chess played on the circular board. In the Byzantine Empire of 11-15 CE it was known in two versions: the regular and the symmetric version. The difference between them: in the latter version the white queen is placed on dark square. However, the computer analysis reveals the effect of this ’perturbation’ as well as the basis of the best winning strategy in both versions. arXiv:math/0701598v2 [math.HO] 4 Oct 2007 1 Introduction Byzantine chess [1], invented about 1000 year ago, is one of the most inter- esting variations of the original chess game Shatranj. It was very popular in Byzantium since 10 CE A.D. (and possible created there). Princess Anna Comnena [2] tells that the emperor Alexius Comnenus played ’Zatrikion’ - so Byzantine scholars called this game. Now it is known under the name of Byzantine chess. 1 Zatrikion or Byzantine chess is the first known attempt to play on the circular board instead of rectangular. The board is made up of four concentric rings with 16 squares (spaces) per ring giving a total of 64 - the same as in the standard 8x8 chessboard. It also contains the same pieces as its parent game - most of the pieces having almost the same moves. In other words divide the normal chessboard in two halves and make a closed round strip [1].
