  2. Data structure - Wikipedia

    en.wikipedia.org/wiki/Data_structure

    A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.

  8. Algorithms for calculating variance - Wikipedia

    en.wikipedia.org/wiki/Algorithms_for_calculating...

    Algorithms for calculating variance play a major role in computational statistics.A key difficulty in the design of good algorithms for this problem is that formulas for the variance may involve sums of squares, which can lead to numerical instability as well as to arithmetic overflow when dealing with large values.

  9. Carry-skip adder - Wikipedia

    en.wikipedia.org/wiki/Carry-skip_adder

    The critical path of a carry-skip-adder begins at the first full-adder, passes through all adders and ends at the sum-bit .Carry-skip-adders are chained (see block-carry-skip-adders) to reduce the overall critical path, since a single -bit carry-skip-adder has no real speed benefit compared to a -bit ripple-carry adder.
