  2. Chess notation - Wikipedia

    en.wikipedia.org/wiki/Chess_notation

    [3] [4] [5] The U.S. Chess Federation prefers the use of algebraic notation but still permits descriptive notation. [6] Long algebraic notation includes the starting file and rank of the piece. Short algebraic notation omits the starting file and rank of the piece, unless it is necessary to disambiguate the move.

  3. File verification - Wikipedia

    en.wikipedia.org/wiki/File_verification

    File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.

  4. Eight queens puzzle - Wikipedia

    en.wikipedia.org/wiki/Eight_queens_puzzle

    If the remainder is 3, move 2 to the end of even list and 1,3 to the end of odd list (4, 6, 8, 2 – 5, 7, 9, 1, 3). Append odd list to the even list and place queens in the rows given by these numbers, from left to right (a2, b4, c6, d8, e3, f1, g7, h5).

  5. Verhoeff algorithm - Wikipedia

    en.wikipedia.org/wiki/Verhoeff_algorithm

    This is actually a single permutation (1 5 8 9 4 2 7 0)(3 6) applied iteratively; i.e. p(i+j,n) = p(i, p(j,n)). The Verhoeff checksum calculation is performed as follows: Create an array n out of the individual digits of the number, taken from right to left (rightmost digit is n 0, etc.). Initialize the checksum c to zero.

    Themes for White: Pressure on the d-file, space advantage, e4–e5 break (often prepared with f2–f4), f2–f4–f5 push, g2–g4–g5 blitz (see Keres Attack). Themes for Black : Pressure on the c-file, minority attack (and counterplay in general) on the queenside, pressure on White's pawn on e4 or e5, d6–d5 break, e6–e5 transposing into ...

  7. Estrin's scheme - Wikipedia

    en.wikipedia.org/wiki/Estrin's_scheme

    In numerical analysis, Estrin's scheme (after Gerald Estrin), also known as Estrin's method, is an algorithm for numerical evaluation of polynomials.. Horner's method for evaluation of polynomials is one of the most commonly used algorithms for this purpose, and unlike Estrin's scheme it is optimal in the sense that it minimizes the number of multiplications and additions required to evaluate ...

  9. Evaluation function - Wikipedia

    en.wikipedia.org/wiki/Evaluation_function

    Games in which game playing computer programs employ evaluation functions include chess, [2] go, [2] shogi (Japanese chess), [2] othello, hex, backgammon, [3] and checkers. [4] [5] In addition, with the advent of programs such as MuZero, computer programs also use evaluation functions to play video games, such as those from the Atari 2600. [6]
