Junior (chess Program)
Junior is a computer chess program written by the Israeli programmers Amir Ban and Shai Bushinsky. Grandmaster Boris Alterman assisted, in particular with the opening book. Junior can take advantage of multiprocessing, multiple processors, taking the name Deep Junior when competing this way in tournaments. According to Bushinsky, one of the innovations of Junior over other chess programs is the way it counts moves. Junior counts orthodox, ordinary moves as two moves, while it counts interesting moves as only one move, or even less. In this way interesting variations are analyzed more meticulously than less promising lines. This seems to be a generalization of search extensions already used by other programs. Another approach its designers claim to use is 'opponent modeling'; Junior might play moves that are not objectively the strongest but that exploit the weaknesses of the opponent. According to Don Dailey "It has some evaluation that can sting if it's in the right situation—t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multiprocessing
Multiprocessing (MP) is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined ( multiple cores on one die, multiple dies in one package, multiple packages in one system unit, etc.). A multiprocessor is a computer system having two or more processing units (multiple processors) each sharing main memory and peripherals, in order to simultaneously process programs. A 2009 textbook defined multiprocessor system similarly, but noted that the processors may share "some or all of the system’s memory and I/O facilities"; it also gave tightly coupled system as a synonymous term. At the operating system level, ''multiprocessing'' is sometimes used to refer to the executi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deep Fritz
Fritz is a German chess program originally developed for Chessbase by Frans Morsch based on his Quest program, ported to DOS, and then Windows by Mathias Feist. With version 13, Morsch retired, and his engine was first replaced by Gyula Horvath's Pandix, and then with Fritz 15, Vasik Rajlich's Rybka. Fritz 17 switched to the Ginkgo engine, written by Frank Schneider. The latest version of the consumer product is Fritz 19. This version supports 64-bit hardware and multiprocessing by default. History In 1991, the German company ChessBase approached the Dutch chess programmer Frans Morsch about writing a chess engine to add to the database program which they sold. Morsch adapted his ''Quest'' program, and ChessBase released it for sale that year as ''Knightstalker'' in the U.S. and Fritz throughout the rest of the world. In 1995, ''Fritz 3'' won the World Computer Chess Championship in Hong Kong, beating an early version of '' Deep Blue''. This was the first time that a prog ...

Rybka
Rybka is a computer chess engine designed by International Master Vasik Rajlich. Around 2011, Rybka was one of the top-rated engines on chess engine rating lists and won many computer chess tournaments. After Rybka won four consecutive World Computer Chess Championships from 2007 to 2010, it was stripped of these titles after the International Computer Games Association concluded in June 2011 that Rybka was plagiarized from both the Crafty and the Fruit chess engines and so failed to meet their originality requirements. In 2015FIDE Ethics Commission following a complaint put forward by Vasik Rajlich and chess engine developer and games publisher Chris Whittington regarding ethical breaches during internal disciplinary proceedings, ruled the ICGA guilty and sanctioned ICGA with a warning. Case 2/2012. ChessBase published a challenging two-part interview-article about the process and verdict with ICGA spokesperson David Levy. Subsequently, ChessBase recruited Rejlich to pro ...

World Microcomputer Chess Championship
World Computer Chess Championship (WCCC) was an event held periodically from 1974 to 2024 where computer chess engines compete against each other. The event is organized by the ''International Computer Games Association'' (ICGA, until 2002 ICCA). It was often held in conjunction with the World Computer Speed Chess Championship and the Computer Olympiad, a collection of computer tournaments for other board games. Instead of using engine protocols, the games are played on physical boards by human operators. The WCCC was open to all types of computers including microprocessors, supercomputers, clusters, and dedicated chess hardware. Due to the requirement to be present on-site, play on a physical board, and strict rules of originality, many strong programs refrain from participating in the ICGA events. As the conditions of the software championship can easily be emulated by anyone with a high-end PC, there are now privately conducted tournaments, such as Top Chess Engine Champions ...
