  2. Mutilated chessboard problem - Wikipedia

    en.wikipedia.org/wiki/Mutilated_chessboard_problem

    The mutilated chessboard problem is an instance of domino tiling of grids and polyominoes, also known as "dimer models", a general class of problems whose study in statistical mechanics dates to the work of Ralph H. Fowler and George Stanley Rushbrooke in 1937. [1] Domino tilings also have a long history of practical use in pavement design and ...

  3. Domino tiling - Wikipedia

    en.wikipedia.org/wiki/Domino_tiling

    Domino tiling. In geometry, a domino tiling of a region in the Euclidean plane is a tessellation of the region by dominoes, shapes formed by the union of two unit squares meeting edge-to-edge. Equivalently, it is a perfect matching in the grid graph formed by placing a vertex at the center of each square of the region and connecting two ...

  4. Domino (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Domino_(mathematics)

    Dominos can tile the plane in a countably infinite number of ways. The number of tilings of a 2×n rectangle with dominoes is , the nth Fibonacci number.. Domino tilings figure in several celebrated problems, including the Aztec diamond problem in which large diamond-shaped regions have a number of tilings equal to a power of two, with most tilings appearing random within a central circular ...

  5. Wang tile - Wikipedia

    en.wikipedia.org/wiki/Wang_tile

    Wang tiles (or Wang dominoes), first proposed by mathematician, logician, and philosopher Hao Wang in 1961, are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them.

    Berger did his undergraduate studies at Rensselaer Polytechnic Institute, and studied applied physics at Harvard, earning a master's degree, before shifting to applied mathematics for his doctorate. Along with Hao Wang, Berger's other two doctoral committee members were Patrick Carl Fischer and Marvin Minsky. Later, he has worked in the Digital ...

  7. Aztec diamond - Wikipedia

    en.wikipedia.org/wiki/Aztec_diamond

    One of 1024 possible domino tilings of an order 4 Aztec diamond A domino tiling of an order-50 Aztec diamond, chosen uniformly at random. The four corners of the diamond outside of the roughly circular area are "frozen". The Aztec diamond theorem states that the number of domino tilings of the Aztec diamond of order n is 2 n(n+1)/2. [2]

  8. Einstein problem - Wikipedia

    en.wikipedia.org/wiki/Einstein_problem

    Aperiodic tiling with "Tile(1,1)". The tiles are colored according to their rotational orientation modulo 60 degrees. [1] ( Smith, Myers, Kaplan, and Goodman-Strauss) In plane geometry, the einstein problem asks about the existence of a single prototile that by itself forms an aperiodic set of prototiles; that is, a shape that can tessellate space but only in a nonperiodic way.

  9. Aperiodic tiling - Wikipedia

    en.wikipedia.org/wiki/Aperiodic_tiling

    An aperiodic tiling using a single shape and its reflection, discovered by David Smith. An aperiodic tiling is a non-periodic tiling with the additional property that it does not contain arbitrarily large periodic regions or patches. A set of tile-types (or prototiles) is aperiodic if copies of these tiles can form only non- periodic tilings.
