Deep Sjeng
Sjeng is a chess engine written by Gian-Carlo Pascutto based on Faile, written by Adrien Regimbald. There are two major versions of Sjeng: the original open source version called Sjeng (also now known as Sjeng old or Sjeng free) and Deep Sjeng, a closed source commercial version. Sjeng ‘Free’ According to the Sjeng website “Sjeng was written by Gian-Carlo Pascutto with help from Adrien Regimbald, Daniel Clausen, Dann Corbit, Lenny Taelman, Ben Nye, Ronald De Man, David Dawson, Tim Foden and Georg von Zimmermann.” The AUTHORS file in the Sjeng distribution states that “Sjeng is written by Gian-Carlo Pascutto, based on work done by Adrien Regimbald.” Unlike most other chess engines Sjeng supports several popular chess variants: Crazyhouse, Suicide, Losers and, when playing on a chess server, Bughouse. Starting with Mac OSX 10.4 Sjeng has been distributed as the engine behind the graphical “Chess” Mac application. The first version with source code under the GPL wa ...

Apple
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple fruit tree, trees are agriculture, cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonization of the Americas, European colonists. Apples have Religion, religious and mythology, mythological significance in many cultures, including Norse mythology, Norse, Greek mythology, Greek, and Christianity in Europe, European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after plantin ...

World Computer 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 on ...

World Computer Speed Chess Championship
World Computer Speed Chess Championship is an annual event organized by the International Computer Games Association where computer chess engines compete against each other at blitz chess time controls. It is held in conjunction with the World Computer Chess Championship. Up to 2001, it was held in conjunction with the World Microcomputer Chess Championships and restricted to microcomputers.

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 ...

Elo Rating
The Elo rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess. It is named after its creator Arpad Elo, a Hungarian-American physics professor. The Elo system was invented as an improved chess-rating system over the previously used Harkness system, but is also used as a rating system in association football, American football, baseball, basketball, pool, table tennis, and various board games and esports. The difference in the ratings between two players serves as a predictor of the outcome of a match. Two players with equal ratings who play against each other are expected to score an equal number of wins. A player whose rating is 100 points greater than their opponent's is expected to score 64%; if the difference is 200 points, then the expected score for the stronger player is 76%. A player's Elo rating is represented by a number which may change depending on the outcome of rated games played. After every game, the winni ...

Multiprocessor
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] |
Bitboard
A bitboard is a specialized bit array data structure commonly used in computer systems that play board games, where each bit corresponds to a game board space or piece. This allows parallel bitwise operations to set or query the game state, or determine moves or plays in the game. Bits in the same bitboard relate to each other by the rules of the game, often forming a game position when taken together. Other bitboards are commonly used as masks to transform or answer queries about positions. Bitboards are applicable to any game whose progress is represented by the state of, or presence of pieces on, discrete spaces of a gameboard, by mapping of the space states to bits in the data structure. Bitboards are a more efficient alternative board representation to the traditional ''mailbox'' representation, where each piece or space on the board is an array element. Bitboards are especially effective when the associated bits of various related states on the board fit into a single wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Google Groups
Google Groups is a service from Google that provides discussion groups for people sharing common interests. The Groups service also provides a gateway to Usenet newsgroups via a shared user interface. Google Groups became operational in February 2001, following Google's acquisition of Deja's Usenet archive. Deja News had been operational since March 1995. Google Groups allows any user to freely conduct and access threaded discussions, via either a web interface or e-mail. There are at least two kinds of discussion group. The first kind are forums specific to Google Groups, which act more like mailing lists. The second kind are Usenet groups, accessible by NNTP, for which Google Groups acts as gateway and unofficial archive. The Google Groups archive of Usenet newsgroup postings dates back to 1981. Through the Google Groups user interface, users can read and post to Usenet groups. In addition to accessing Google and Usenet groups, registered users can also set up mailing list ar ...
