Battleship (puzzle)
The Battleship puzzle (sometimes called Bimaru, Yubotu, Solitaire Battleships or Battleship Solitaire) is a logic puzzle based on the Battleship guessing game. It and its variants have appeared in several puzzle contests, including the World Puzzle Championship, and puzzle magazines, such as ''Games'' magazine. Solitaire Battleship was invented in Argentina by Jaime Poniachik and was first featured in 1982 in the Argentine magazine '. Battleship gained more widespread popularity after its international debut at the first World Puzzle Championship in New York City in 1992. Battleship appeared in ''Games'' magazine the following year and remains a regular feature of the magazine. Variants of Battleship have emerged since the puzzle's inclusion in the first World Puzzle Championship. Battleship is played in a grid of squares that hides ships of different sizes. Numbers alongside the grid indicate how many squares in a row or column are occupied by part of a ship. History The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battleship (game)
''Battleship'' (also known as ''Battleships'') is a strategy type guessing game for two players. It is played on ruled grids (paper or board) on which each player's fleet of warships are marked. The locations of the fleets are concealed from the other player. Players alternate turns calling "shots" at the other player's ships, and the objective of the game is to destroy the opposing player's fleet. ''Battleship'' is known worldwide as a pencil and paper game which dates from World War I. It was published by various companies as a pad-and-pencil game in the 1930s and was released as a plastic board game by Milton Bradley in 1967. The game has spawned electronic versions, video games, smart device apps and a film. History The game of ''Battleship'' is thought to have its origins in the French game '' L'Attaque'' played during World War I, although parallels have also been drawn to E. I. Horsman's 1890 game Basilinda, and the game is said to have been played by Russian offic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Puzzle Championship
The World Puzzle Championship (commonly abbreviated as WPC) is an annual international puzzle competition run by the World Puzzle Federation. All the puzzles in the competition are pure-logic problems based on simple principles, designed to be playable regardless of language or culture. National teams are determined by local affiliates of the World Puzzle Federation. Of the 30 championships (team category) held thus far, 16 have been won by the United States, 8 by Germany, and 3 each by the Czech Republic and Japan. The most successful individual contestant is Ulrich Voigt (Germany) with 11 titles since 2000. The latest WPC was held in October 2024 in Beijing. Origin The World Puzzle Championship was the brainchild of Levi Summers, who wanted to create an event where puzzlers from different countries could compete on an even playing field. Previously, the International Crossword Marathon was the major international competition for puzzle-solving, and Will Shortz had attended ...

Games (magazine)
''Games World of Puzzles'' is an American games and puzzle magazine. Originally the merger of two other puzzle magazines spun off from its parent publication ''Games'' magazine in the early 1990s, ''Games World of Puzzles'' was reunited with ''Games'' in October 2014. The entire magazine interior is now newsprint (as opposed to the part-glossy/part-newsprint format of the original ''Games'') and the puzzles and articles that originally sandwiched the "Pencilwise" section are now themselves sandwiched ''by'' the main puzzle pages, replacing the "feature puzzle" section (they are still full-color, unlike the two-color "Pencilwise" sections.) The recombined title assumed the same 9-issue-per-year publication schedule as the original ''Games''. ''Games'' ''Games'' () was a magazine devoted to games and puzzles and, until its 2014 merger was published by Games Publications, a division of Kappa Publishing Group. History ''Games'' debuted with its September/October 1977 issue, publi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solitaire (game)
Patience (Europe), card solitaire, or solitaire (US/Canada), is a genre of card games whose common feature is that the aim is to arrange the cards in some systematic order or, in a few cases, to pair them off in order to discard them. Most are intended for play by a single player, but there are varieties for two or more players. Genre names 'Patience' is the earliest recorded name for this type of card game in both British and American sources. The word derives from the games being seen as an exercise in patience.Parlett (1991), pp. 157–161. Although the name solitaire became common in North America for this type of game during the 20th century, British games scholar David Parlett argues that there are good reasons for preferring the name 'patience'. Firstly, ''patience'' refers specifically to card games, whereas ''solitaire'' may also refer to games played with dominoes or peg and board games. Secondly, any game of patience may be played competitively by two or more player ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battleship
A battleship is a large, heavily naval armour, armored warship with a main battery consisting of large naval gun, guns, designed to serve as a capital ship. From their advent in the late 1880s, battleships were among the largest and most formidable weapon systems ever built, until they were surpassed by aircraft carriers beginning in the 1940s. The modern battleship traces its origin to the sailing ship of the line, which was developed into the steam ship of the line and soon thereafter the ironclad warship. After a period of extensive experimentation in the 1870s and 1880s, ironclad design was largely standardized by the British , which are usually referred to as the first "pre-dreadnought battleships". These ships carried an armament that usually included four large guns and several medium-caliber guns that were to be used against enemy battleships, and numerous small guns for self-defense. Naval powers around the world built dozens of pre-dreadnoughts in the 1890s and early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea denial. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—usually fulfilled by frigates or sloop-of-war, sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre- ...

Destroyer
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were conceived in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unatte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

NP-complete
In computational complexity theory, NP-complete problems are the hardest of the problems to which ''solutions'' can be verified ''quickly''. Somewhat more precisely, a problem is NP-complete when: # It is a decision problem, meaning that for any input to the problem, the output is either "yes" or "no". # When the answer is "yes", this can be demonstrated through the existence of a short (polynomial length) ''solution''. # The correctness of each solution can be verified quickly (namely, in polynomial time) and a brute-force search algorithm can find a solution by trying all possible solutions. # The problem can be used to simulate every other problem for which we can verify quickly that a solution is correct. Hence, if we could find solutions of some NP-complete problem quickly, we could quickly find the solutions of every other problem to which a given solution can be easily verified. The name "NP-complete" is short for "nondeterministic polynomial-time complete". In this name, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ICGA Journal
The ''ICGA Journal'' is a quarterly academic journal published by the International Computer Games Association. It was renamed in 2000. Its previous name was the ''ICCA Journal'' of the International Computer Chess Association, which was founded in 1977. The journal covers computer analysis on two-player games, especially games with perfect information such as chess, checkers, and Go. It has been the primary outlet for publication of articles on solved games, including the development of endgame tablebases in chess and other games. For example, John W. Romein and Henri E. Bal reported in the journal in 2002 that they had solved Awari and, in 2015, David J. Wu reported his solution for the Arimaa Challenge.{{cite journal , first=David J. , last=Wu , year=2015 , title=Designing a Winning Arimaa Program , journal=ICGA Journal , volume=38 , number=1 , pages=19–40 , doi=10.3233/ICG-2015-38104 , url=https://icosahedral.net/downloads/djwu2015arimaa.pdf From 1983 till 2015 ''ICGA J ...
