[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.

4 − 5 × 6: The multiplication must be done first, and the formula has to be rearranged and calculated as −5 × 6 + 4. So ± and addition have to be used rather than subtraction. When + is pressed, the multiplication is performed. 4 × (5 + 6): The
If the claim for a draw is incorrect, the opponent is awarded an extra two minutes, the written move (if legal) move must be played and the game continues. [4] Unreasonable claims may be penalized under rule 11.5, which forbids distracting or annoying the opponent. [ 5 ]

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]
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 ...
