Amir Ban
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 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—that no other pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Chess
Computer chess includes both hardware (dedicated computers) and software capable of playing chess. Computer chess provides opportunities for players to practice even in the absence of human opponents, and also provides opportunities for analysis, entertainment and training. Computer chess applications that play at the level of a chess master or higher are available on hardware from supercomputers to smart phones. Standalone chess-playing machines are also available. Stockfish, GNU Chess, Fruit, and other free open source applications are available for various platforms. Computer chess applications, whether implemented in hardware or software, utilize different strategies than humans to choose their moves: they use heuristic methods to build, search and evaluate trees representing sequences of moves from the current position and attempt to execute the best such sequence during play. Such trees are typically quite large, thousands to millions of nodes. The computational speed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multiprocessing
Multiprocessing 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.). According to some on-line dictionaries, 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 noting 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 som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Don Dailey
Don Dailey (March 10, 1956 – November 22, 2013) was an American longtime researcher in computer chess and a game programmer. Along with collaborator Larry Kaufman, he was the author of the chess engine Komodo. Dailey started chess programming in the 1980s, and was the author and co-author of multiple commercial as well as academic chess programs. He has been an active poster in computer chess forums and computer Go newsgroups. He was raised as a Jehovah's Witness and served in recent years as an elder in the church of Roanoke.

Thoresen Chess Engines Competition
Top Chess Engine Championship, formerly known as Thoresen Chess Engines Competition (TCEC or nTCEC), is a computer chess tournament that has been run since 2010. It was organized, directed, and hosted by Martin Thoresen until the end of Season 6; from Season 7 onward it has been organized by Chessdom. It is often regarded as the ''Unofficial World Computer Chess Championship'' because of its strong participant line-up and long time-control matches on high-end hardware, giving rise to very high-class chess. The tournament has attracted nearly all the top engines compared to the World Computer Chess Championship. After a short break in 2012, TCEC was restarted in early 2013 (as ''nTCEC'') and is currently active (renamed as TCEC in early 2014) with 24/7 live broadcasts of chess matches on its website. Since season 5, TCEC has been sponsored by Chessdom Arena. Overview Basic structure of competition The TCEC competition is divided into seasons, where each season happens over a cours ...

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. The latest version of the consumer product is Fritz 18 Neuronal. 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 program running on a consumer-level microcomputer defeated the mainf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 has published Rybka to prod ...

World Microcomputer Chess Championship
World Computer Chess Championship (WCCC) is an event held periodically since 1974 where computer chess engines compete against each other. The event is organized by the International Computer Games Association. It is 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 is open to all types of computers including microprocessors, supercomputers, clusters, and dedicated chess hardware. Championship results In 2007, the reigning champion Junior declined to defend its title. For the 2009 edition, the rules were changed to limit platforms to commodity hardware supporting at most eight cores, thereby excluding supercomputers and large clusters. However, this was reversed in the following year and a parallel Software Championship was held instead; unlimited hardware is onc ...
