Preface About five years ago I completed my diploma project about computer chess at the University of Applied Sciences in Friedberg, Germany. Immediately after- wards I continued in 2004 with the R&D of my computer-chess engine Loop. In 2005 I started my Ph.D. project ”New Architectures in Computer Chess” at the Maastricht University. In the first year of my R&D I concentrated on the redesign of a computer-chess architecture for 32-bit computer environments. -
A Chess Engine
A Chess Engine Paul Dailly Dominik Gotojuch Neil Henning Keir Lawson Alec Macdonald Tamerlan Tajaddinov University of Glasgow Department of Computing Science Sir Alwyn Williams Building Lilybank Gardens Glasgow G12 8QQ March 18, 2008 Abstract Though many computer chess engines are available, the number of engines using object orientated approaches to the problem is minimal. This report documents an implementation of an object oriented chess engine. Traditionally, in order to gain the advantage of speed, the C language is used for implementation, however, being an older language, it lacks many modern language features. The chess engine documented within this report uses the modern Java language, providing features such as reflection and generics that are used extensively, allowing for complex but understandable code. Also of interest are the various depth first search algorithms used to produce a fast game, and the numerous functions for evaluating different characteristics of the board. These two fundamental components, the evaluator and the analyser, combine to produce a fast and relatively skillful chess engine. We discuss both the design and implementation of the engine, along with details of other approaches that could be taken, and in what manner the engine could be expanded. We conclude by examining the engine empirically, and from this evaluation, reflecting on the advantages and disadvantages of our chosen approach.

Get in Touch with Jaap Van Den Herik
28 ICCA Journal March 1992 NEWS, INFORMATION, TOURNAMENTS AND REPORTS A DATABASE AS A SECOND D.M. Breuker L.v. Allis I.S. Herschberg H.J. van den Herik University of Limburg Delft Unversity of Technology Dept. of Computer Science Dept. of Technical Mathematics Maastricht, The Netherlands and Informatics Delft, The Netherlands ABSTRACT Chess endgame databases have provided computer-chess researchers with perfect knowledge of many endgames. Grandmaster play, however, has been largely unaffected by their existence. In the 1992 Linares tournament, Timman and Speelman adjourned a posi- tion which could lead to the KBBKN endgame. With the aid of publications on computer analysis of this endgame, Timman successfully prepared for the human-to-human confronta- tion and defeated Speelman. This contribution describes the background of the KBBKN endgame, the sequence of events which led to Timman's victory, and presents analyses of the grandmasters' performance. 1. BACKGROUND More than a century ago, Kling and Horwitz (1851) published the first thorough study of the KBBKN endgame. Their analysis showed that in the position of Diagram 1, Black can hold out indefinitely against White's attacks. They concluded that King and two Bishops cannot win if the weaker side can obtain the posi- tion of Diagram 1. The essential feature of this position is the King and the Knight's making up a fortress near a comer of the board, it being crucial that the Knight is on b7; this essence is maintained upon reflection in one or both of the board's medial lines. Kling and Horwitz (1851) asserted that Diagram 1 and its reflections pro- vided an exception, and that, Black failing to achieve Diagram I, White was bound to win. -

Chess As Played by Artificial Intelligence
Chess as Played by Artificial Intelligence Filemon Jankuloski, Adrijan Božinovski1 University American College of Skopje, Skopje, Macedonia [email protected] [email protected] Abstract. In this paper, we explore the evolution of how chess machinery plays chess. The purpose of the paper is to discuss the several different algorithms and methods which are implemented into chess machinery systems to either make chess playing more efficient or increase the playing strength of said chess machinery. Not only do we look at methods and algorithms implemented into chess machinery, but we also take a look at the many accomplishments achieved by these machines over a 70 year period. We will analyze chess machines from their conception up until their absolute domination of the competitive chess scene. This includes chess machines which utilize anything from brute force approaches to deep learning and neural networks. Finally, the paper is concluded by discussing the future of chess machinery and their involvement in both the casual and competitive chess scene. Keywords: Chess · Algorithm · Search · Artificial Intelligence 1 Introduction Artificial intelligence has become increasingly prevalent in our current society. We can find artificial intelligence being used in many aspects of our daily lives, such as through the use of Smartphones and autonomous driving vehicles such as the Tesla. There is no clear and concise definition for Artificial Intelligence, since it is a subject which still has massive space for improvement and has only recently been making most of its significant advancements. Leading textbooks on AI, however, define it as the study of “intelligent agents”, which can be represented by any device that perceives its environment and takes actions that maximizes its chances of achieving its goals [1]. -
An Historical Perspective Through the Game of Chess
On the Impact of Information Technologies on Society: an Historical Perspective through the Game of Chess Fr´ed´eric Prost LIG, Universit´ede Grenoble B. P. 53, F-38041 Grenoble, France [email protected] Abstract The game of chess as always been viewed as an iconic representation of intellectual prowess. Since the very beginning of computer science, the challenge of being able to program a computer capable of playing chess and beating humans has been alive and used both as a mark to measure hardware/software progresses and as an ongoing programming challenge leading to numerous discoveries. In the early days of computer science it was a topic for specialists. But as computers were democratized, and the strength of chess engines began to increase, chess players started to appropriate to themselves these new tools. We show how these interac- tions between the world of chess and information technologies have been herald of broader social impacts of information technologies. The game of chess, and more broadly the world of chess (chess players, literature, computer softwares and websites dedicated to chess, etc.), turns out to be a surprisingly and particularly sharp indicator of the changes induced in our everyday life by the information technologies. Moreover, in the same way that chess is a modelization of war that captures the raw features of strategic thinking, chess world can be seen as small society making the study of the information technologies impact easier to analyze and to arXiv:1203.3434v1 [cs.OH] 15 Mar 2012 grasp.
