  3. Spigot algorithm - Wikipedia

    en.wikipedia.org/wiki/Spigot_algorithm

    A variant of the spigot approach uses an algorithm which can be used to compute a single arbitrary digit of the transcendental without computing the preceding digits: an example is the Bailey–Borwein–Plouffe formula, a digit extraction algorithm for π which produces base 16 digits. The inevitable truncation of the underlying infinite ...

  4. Dekker's algorithm - Wikipedia

    en.wikipedia.org/wiki/Dekker's_algorithm

    Dekker's algorithm is the first known correct solution to the mutual exclusion problem in concurrent programming where processes only communicate via shared memory. The solution is attributed to Dutch mathematician Th. J. Dekker by Edsger W. Dijkstra in an unpublished paper on sequential process descriptions [1] and his manuscript on cooperating sequential processes. [2]

  5. Eisenberg & McGuire algorithm - Wikipedia

    en.wikipedia.org/wiki/Eisenberg_&_McGuire_algorithm

    The variable turn is set arbitrarily to a number between 0 and n−1 at the start of the algorithm. The flags variable for each process is set to WAITING whenever it intends to enter the critical section. flags takes either IDLE or WAITING or ACTIVE. Initially the flags variable for each process is initialized to IDLE.

  6. 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.

  7. Gauss–Legendre algorithm - Wikipedia

    en.wikipedia.org/wiki/Gauss–Legendre_algorithm

    The Gauss–Legendre algorithm is an algorithm to compute the digits of π. It is notable for being rapidly convergent, with only 25 iterations producing 45 million correct digits of π . However, it has some drawbacks (for example, it is computer memory -intensive) and therefore all record-breaking calculations for many years have used other ...

  8. Lamport's bakery algorithm - Wikipedia

    en.wikipedia.org/wiki/Lamport's_bakery_algorithm

    When implementing the pseudo code in a single process system or under cooperative multitasking, it is better to replace the "do nothing" sections with code that notifies the operating system to immediately switch to the next thread. This primitive is often referred to as yield. Lamport's bakery algorithm assumes a sequential consistency memory ...

  9. π-calculus - Wikipedia

    en.wikipedia.org/wiki/Π-calculus

    The π-calculus belongs to the family of process calculi, mathematical formalisms for describing and analyzing properties of concurrent computation.In fact, the π-calculus, like the λ-calculus, is so minimal that it does not contain primitives such as numbers, booleans, data structures, variables, functions, or even the usual control flow statements (such as if-then-else, while).
