2. Trachtenberg system - Wikipedia

   en.wikipedia.org/wiki/Trachtenberg_system

   Trachtenberg system. The Trachtenberg system is a system of rapid mental calculation. The system consists of a number of readily memorized operations that allow one to perform arithmetic computations very quickly. It was developed by the Russian engineer Jakow Trachtenberg in order to keep his mind occupied while being in a Nazi concentration camp.

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. Standard algorithms - Wikipedia

   en.wikipedia.org/wiki/Standard_algorithms

   For computer algorithms, see List of algorithms. In elementary arithmetic, a standard algorithm or method is a specific method of computation which is conventionally taught for solving particular mathematical problems. These methods vary somewhat by nation and time, but generally include exchanging, regrouping, long division, and long ...

5. Algorithm - Wikipedia

   en.wikipedia.org/wiki/Algorithm

   In mathematics and computer science, an algorithm (/ ˈælɡərɪðəm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation. [ 1 ] Algorithms are used as specifications for performing calculations and data processing.

6. Sieve of Eratosthenes - Wikipedia

   en.wikipedia.org/wiki/Sieve_of_Eratosthenes

   Here the example is shown starting from odds, after the first step of the algorithm. Thus, on the k th step all the remaining multiples of the k th prime are removed from the list, which will thereafter contain only numbers coprime with the first k primes (cf. wheel factorization ), so that the list will start with the next prime, and all the ...

7. Greedy algorithm - Wikipedia

   en.wikipedia.org/wiki/Greedy_algorithm

   The matching pursuit is an example of a greedy algorithm applied on signal approximation. A greedy algorithm finds the optimal solution to Malfatti's problem of finding three disjoint circles within a given triangle that maximize the total area of the circles; it is conjectured that the same greedy algorithm is optimal for any number of circles.
