  2. Cooley–Tukey FFT algorithm - Wikipedia

    en.wikipedia.org/wiki/Cooley–Tukey_FFT_algorithm

    The Cooley–Tukey algorithm, named after J. W. Cooley and John Tukey, is the most common fast Fourier transform (FFT) algorithm. It re-expresses the discrete Fourier transform (DFT) of an arbitrary composite size = in terms of N 1 smaller DFTs of sizes N 2, recursively, to reduce the computation time to O(N log N) for highly composite N (smooth numbers).

  3. List of algorithms - Wikipedia

    en.wikipedia.org/wiki/List_of_algorithms

    An algorithm is fundamentally a set of rules or defined procedures that is typically designed and used to solve a specific problem or a broad set of problems.. Broadly, algorithms define process(es), sets of rules, or methodologies that are to be followed in calculations, data processing, data mining, pattern recognition, automated reasoning or other problem-solving operations.

  4. Pomodoro Technique - Wikipedia

    en.wikipedia.org/wiki/Pomodoro_Technique

    Set the Pomodoro timer (typically for 25 minutes). [1] Work on the task. End work when the timer rings and take a short break (typically 5–10 minutes). [5] Go back to Step 2 and repeat until you complete four pomodori. After four pomodori are done, take a long break (typically 20 to 30 minutes) instead of a short break.

  5. Sorting algorithm - Wikipedia

    en.wikipedia.org/wiki/Sorting_algorithm

    For example, if any number of elements are out of place by only one position (e.g. 0123546789 and 1032547698), bubble sort's exchange will get them in order on the first pass, the second pass will find all elements in order, so the sort will take only 2n time.

  6. Counting sort - Wikipedia

    en.wikipedia.org/wiki/Counting_sort

    Bucket sort may be used in lieu of counting sort, and entails a similar time analysis. However, compared to counting sort, bucket sort requires linked lists, dynamic arrays, or a large amount of pre-allocated memory to hold the sets of items within each bucket, whereas counting sort stores a single number (the count of items) per bucket. [4]

  7. Countdown - Wikipedia

    en.wikipedia.org/wiki/Countdown

    In the context of a rocket launch, the "L minus Time" is the physical time before launch, e.g. "L minus 3 minutes and 40 seconds". "T minus Time" is a system to mark points at which actions necessary for the launch are planned - this time stops and starts as various hold points are entered, and so doesn't show the actual time to launch.

  8. Exponential backoff - Wikipedia

    en.wikipedia.org/wiki/Exponential_backoff

    If that fails, resend the frame after either 0 s, 51.2 μs, 102.4 μs, or 153.6 μs. If that still fails, resend the frame after k · 51.2 μs, where k is a random integer between 0 and 2 3 − 1. For further failures, after the cth failed attempt, resend the frame after k · 51.2 μs, where k is a random integer between 0 and 2 c − 1.

  9. Change-making problem - Wikipedia

    en.wikipedia.org/wiki/Change-making_problem

    Coin values can be modeled by a set of n distinct positive integer values (whole numbers), arranged in increasing order as w 1 through w n.The problem is: given an amount W, also a positive integer, to find a set of non-negative (positive or zero) integers {x 1, x 2, ..., x n}, with each x j representing how often the coin with value w j is used, which minimize the total number of coins f(W)
