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 or Sea Battle) 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 o ... [...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 26 championships (team category) held thus far, 14 have been won by the United States, 7 by Germany, 3 by the Czech Republic, and 2 by Japan. The most successful individual contestant is Ulrich Voigt (Germany) with 11 titles since 2000. The latest WPC was held in October 2019 in Germany. 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 Shortz had attended it every ...

Games (magazine)
''GAMES World of Puzzles'' is a puzzle magazine formed from the merger of Games and World of Puzzles 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.) Like the original ''World of Puzzles'' (which is now discontinued), the answer key is now at the rear of the magazine. The new combined title remained on the same 9-issue-per-year publication schedule as the original ''Games''. Games ''Games'' magazine (ISSN 0199-9788) was a magazine devoted to games and puzzles, and it was published by Games Publications, a division of Kappa Publishing Group. History Games was originally published by ''Playboy'' (debuting with the September/October 1977 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solitaire
Solitaire is any tabletop game which one can play by oneself, usually with cards, but also with dominoes. The term "solitaire" is also used for single-player games of concentration and skill using a set layout tiles, pegs or stones. These games include peg solitaire and mahjong solitaire. The game is most often played by one person, but can incorporate others. History The origins of Card Solitaire or Patience are unclear, but the earliest records appear in the late 1700s across northern Europe and Scandinavia. The term ''Patiencespiel'' appears in ''Das neue Königliche L’Hombre-Spiel'', a German book published in 1788. Books were also reported to appear in Sweden and Russia in the early 1800s. There are additional references to Patience in French literature. In the United States, the first card solitaire book, ''Patience: A series of thirty games with cards'', was published by Ednah Cheney in 1870. The most popular card solitaire is Klondike, which was called Microsoft So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battleship
A battleship is a large armored warship with a main battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', .

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 roles. 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—fulfilled by frigates or 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-dreadnought battleship. With the advent of the dreadnought battleship before World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed 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 unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Horizontal Plane
In astronomy, geography, and related sciences and contexts, a '' direction'' or ''plane'' passing by a given point is said to be vertical if it contains the local gravity direction at that point. Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system. Historical definition The word ''horizontal'' is derived from the Latin , which derives from the Greek , meaning 'separating' or 'marking a boundary'. The word ''vertical'' is derived from the late Latin ', which is from the same root as ''vertex'', meaning 'highest point' or more literally the 'turning point' such as in a whirlpool. Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book ''Perspective''.

NP-complete
In computational complexity theory, a problem is NP-complete when: # it is a problem for which 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. In this sense, NP-complete problems are the hardest of the problems to which solutions can be verified quickly. 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, "nondeterministic" refers to nondeterministic Turing machines, a way of mathematically formalizing the idea of a brute-force search algorithm. Polynomial time refers to an amount of time that is considered "quick" for a de ... [...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 Jou ...
