Sokoban Ani
is a puzzle video game in which the player pushes boxes around in a warehouse, trying to get them to storage locations. The game was designed in 1981 by Hiroyuki Imabayashi and first published in Japan in 1982 by his company Thinking Rabbit for the NEC PC-8801 computer. It was later ported to various platforms and followed by new titles. It became popular in Japan and internationally, inspiring unofficial versions, a subgenre of box-pushing puzzle games, and artificial intelligence research. Gameplay The warehouse is a grid composed of floor squares and impassable wall squares. Some floor squares contain a box and some are marked as storage locations. The number of boxes equals the number of storage locations. The player, often represented as a worker character, can move one square at a time horizontally or vertically onto empty floor squares, but cannot pass through walls or boxes. To move a box, the player walks up to it and pushes it to an empty square directly beyond the b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puzzle Video Game
Puzzle video games make up a broad genre of video games that emphasize puzzle solving. The types of puzzles can test problem-solving skills, including logic, pattern recognition, Sequence, sequence solving, Spatial ability, spatial recognition, and word completion. Many puzzle games involve a real-time element and require quick thinking, such as ''Tetris'' (1985) and ''Lemmings (video game), Lemmings'' (1991). History Puzzle video games owe their origins to brain teasers and puzzles throughout human history. The mathematical strategy game Nim, and other traditional thinking games such as Hangman (game), Hangman and Bulls and Cows (commercialized as ''Mastermind (board game), Mastermind''), were popular targets for computer implementation. In Universal Entertainment's ''Space Panic'', released in arcades in 1980, the player digs holes in platforms to trap creatures. It is a precursor to puzzle-platform games such as ''Lode Runner'' (1983), ''Door Door'' (1983), and ''Doki Dok ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Famicom Disk System
The commonly shortened to the Famicom Disk System, is a peripheral for Nintendo's Family Computer (Famicom) home video game console, released in Japan on February 21, 1986. The system uses proprietary floppy disks called "Disk Cards" for more affordable data storage and adds a high-fidelity sound channel to enhance audio in compatible Disk System games. To support the Disk System, Nintendo installed "Disk Writer" kiosks in stores across Japan that allowed customers to bring their Disk Cards and have new games rewritten onto them for a small fee, making it a cost-effective alternative to purchasing games on traditional RAM cartridges. Nintendo also offered similar disk rewriting services by mail. The Disk System was designed to enhance features already present in the base Famicom, offering better sound and cheaper, rewritable games. However, it came with drawbacks, including a high initial price for the device along with the storage medium's slower load times and reduced relia ...

Computational Complexity Theory
In theoretical computer science and mathematics, computational complexity theory focuses on classifying computational problems according to their resource usage, and explores the relationships between these classifications. A computational problem is a task solved by a computer. A computation problem is solvable by mechanical application of mathematical steps, such as an algorithm. A problem is regarded as inherently difficult if its solution requires significant resources, whatever the algorithm used. The theory formalizes this intuition, by introducing mathematical models of computation to study these problems and quantifying their computational complexity, i.e., the amount of resources needed to solve them, such as time and storage. Other measures of complexity are also used, such as the amount of communication (used in communication complexity), the number of logic gate, gates in a circuit (used in circuit complexity) and the number of processors (used in parallel computing).

Hexagonal Tiling
In geometry, the hexagonal tiling or hexagonal tessellation is a regular tiling of the Euclidean plane, in which exactly three hexagons meet at each vertex. It has Schläfli symbol of or (as a Truncation (geometry), truncated triangular tiling). English mathematician John Horton Conway, John Conway called it a hextille. The internal angle of the hexagon is 120 degrees, so three hexagons at a point make a full 360 degrees. It is one of List of regular polytopes#Euclidean tilings, three regular tilings of the plane. The other two are the triangular tiling and the square tiling. Structure and properties The hexagonal tiling has a structure consisting of a regular hexagon only as its prototile, sharing two vertices with other identical ones, an example of monohedral tiling. Each vertex at the tiling is surrounded by three regular hexagons, denoted as 6.6.6 by vertex configuration. The dual of a hexagonal tiling is triangular tiling, because the center of each hexagonal tiling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tessellation
A tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called ''tiles'', with no overlaps and no gaps. In mathematics, tessellation can be generalized to higher dimensions and a variety of geometries. A periodic tiling has a repeating pattern. Some special kinds include '' regular tilings'' with regular polygonal tiles all of the same shape, and '' semiregular tilings'' with regular tiles of more than one shape and with every corner identically arranged. The patterns formed by periodic tilings can be categorized into 17 wallpaper groups. A tiling that lacks a repeating pattern is called "non-periodic". An '' aperiodic tiling'' uses a small set of tile shapes that cannot form a repeating pattern (an aperiodic set of prototiles). A '' tessellation of space'', also known as a space filling or honeycomb, can be defined in the geometry of higher dimensions. A real physical tessellation is a tiling made of materials such as ...

Square Tiling
In geometry, the square tiling, square tessellation or square grid is a regular tiling of the Euclidean plane consisting of four squares around every vertex. John Horton Conway called it a quadrille. Structure and properties The square tiling has a structure consisting of one type of congruent prototile, the square, sharing two vertices with other identical ones. This is an example of monohedral tiling. Each vertex at the tiling is surrounded by four squares, which denotes in a vertex configuration as 4.4.4.4 or 4^4 . The vertices of a square can be considered as the lattice, so the square tiling can be formed through the square lattice. This tiling is commonly familiar with the flooring and game boards. It is self-dual, meaning the center of each square connects to another of the adjacent tile, forming square tiling itself. The square tiling acts transitively on the ''flags'' of the tiling. In this case, the flag consists of a mutually incident vertex, edge, and tile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Gaming World
''Computer Gaming World'' (CGW) was an American Video game journalism, computer game magazine that was published between 1981 and 2006. One of the few magazines of the era to survive the video game crash of 1983, it was sold to Ziff Davis in 1993. It expanded greatly through the 1990s and became one of the largest dedicated video game magazines, reaching around 500 pages by 1997. In the early 2000s its circulation was about 300,000, only slightly behind the market leader ''PC Gamer''. But, like most magazines of the era, the rapid move of its advertising revenue to internet properties led to a decline in revenue. In 2006, Ziff announced it would be refocused as ''Games for Windows: The Official Magazine, Games for Windows'', before moving it to solely online format, and then shutting down completely later the same year. History In 1979, Russell Sipe left the Southern Baptist Convention ministry. A fan of computer games, he realized in Spring, 1981 that no Video game journalism, ...

TurboGrafx-16
The TurboGrafx-16, known in Japan as the , is a home video game console developed by Hudson Soft and manufactured by NEC. It was released in Japan in 1987 and in North America in 1989. The first console of the fourth generation of video game consoles, fourth generation, it launched in Japan to compete with Nintendo's Family Computer, Famicom, but its delayed U.S. debut placed it against the more advanced Sega Genesis and later the Super Nintendo Entertainment System, Super NES. The TurboGrafx-16 features an 8-bit computing, 8-bit CPU paired with dual 16-bit graphics processors, and supports up to 482 on-screen colors from a palette of 512. The "16" in the console’s North American branding was criticized as misleading. With dimensions of , the PC Engine remains the smallest major home console ever released. Games were initially released on HuCard cartridges, but the platform later supported additional formats requiring separate hardware: TurboGrafx-CD (''CD-ROM²'' in Japan) ga ...

NEC PC-9801
The , commonly shortened to PC-98 or simply , is a lineup of Japanese 16-bit and 32-bit Personal computer, personal computers manufactured by NEC from 1982 to 2003. While based on Intel processors, it uses an in-house architecture making it incompatible with IBM PC–compatible, IBM clones; some PC-98 computers used NEC's own NEC V30, V30 processor. The platform established NEC's dominance in the Japanese personal computer market, and, by 1999, more than 18 million units had been sold. While NEC did not market these specific machines in the West, it sold the NEC APC series, which had similar hardware to early PC-98 models. The PC-98 was initially released as a business-oriented personal computer which had backward compatibility with the successful PC-8800 series. The range of the series was expanded, and in the 1990s it was used in a variety of industry fields including education and hobbies. NEC succeeded in attracting third-party suppliers and a wide range of users, and the PC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM Personal Computer AT
The IBM Personal Computer AT (model 5170, abbreviated as IBM AT or PC/AT) was released in 1984 as the fourth model in the IBM Personal Computer line, following the IBM PC/XT and its IBM Portable PC variant. It was designed around the Intel 80286 microprocessor. Name IBM did not specify an expanded form of ''AT'' on the machine, press releases, brochures or documentation, but some sources expand the term as ''Advanced Technology'', including at least one internal IBM document. History IBM's 1984 introduction of the AT was seen as an unusual move for the company, which typically waited for competitors to release new products before producing its own models. At $4,000–6,000, it was only slightly more expensive than considerably slower IBM models. The announcement surprised rival executives, who admitted that matching IBM's prices would be difficult. No major competitor showed a comparable computer at COMDEX Las Vegas that year. Features The AT is IBM PC compatible, with ...
