    [82] [83] Thus, a formula counting dates between (for example) February 1, 1900 and March 1, 1900 will return an incorrect result. The bug originated from Lotus 1-2-3 , where it was deliberately implemented to save computer memory, and was also intentionally implemented in Excel for the purpose of bug compatibility . [ 84 ]

    One discrete problem that is expensive to solve on many computers is that of counting the number of bits that are set to 1 in a (binary) number, sometimes called the population function. For example, the decimal number "37" is "00100101" in binary, so it contains three bits that are set to binary "1". [7]: 282

    A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings , or for input validation .

    A molecular formula enumerates the number of atoms to reflect those in the molecule, so that the molecular formula for glucose is C 6 H 12 O 6 rather than the glucose empirical formula, which is CH 2 O. Except for the very simple substances, molecular chemical formulas generally lack needed structural information, and might even be ambiguous in ...

    However, the CBOW is less computationally expensive and yields similar accuracy results. [1] Overall, accuracy increases with the number of words used and the number of dimensions. Mikolov et al. [1] report that doubling the amount of training data results in an increase in computational complexity equivalent to doubling the number of vector ...
