  2. Petrick's method - Wikipedia

    en.wikipedia.org/wiki/Petrick's_method

    Based on the marks in the table above, build a product of sums of the rows. Each column of the table makes a product term which adds together the rows having a mark in that column: (K+L)(K+M)(L+N)(M+P)(N+Q)(P+Q) Use the distributive law to turn that expression into a sum of products.

  3. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows. This diagrammatic representation illustrates a solution model to a given problem.

  4. Conjugate gradient method - Wikipedia

    en.wikipedia.org/wiki/Conjugate_gradient_method

    Starting with an initial guess x 0, this means we take p 0 = b − Ax 0. The other vectors in the basis will be conjugate to the gradient, hence the name conjugate gradient method. Note that p 0 is also the residual provided by this initial step of the algorithm. Let r k be the residual at the kth step:

  5. Algorithm - Wikipedia

    en.wikipedia.org/wiki/Algorithm

    Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.

  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. Gaussian elimination - Wikipedia

    en.wikipedia.org/wiki/Gaussian_elimination

    Animation of Gaussian elimination. Red row eliminates the following rows, green rows change their order. In mathematics, Gaussian elimination, also known as row reduction, is an algorithm for solving systems of linear equations. It consists of a sequence of row-wise operations performed on the corresponding matrix of coefficients.

  8. Dantzig–Wolfe decomposition - Wikipedia

    en.wikipedia.org/wiki/Dantzig–Wolfe_decomposition

    The master program incorporates one or all of the new columns generated by the solutions to the subproblems based on those columns' respective ability to improve the original problem's objective. Master program performs x iterations of the simplex algorithm, where x is the number of columns incorporated. If objective is improved, goto step 1.

  9. Quine–McCluskey algorithm - Wikipedia

    en.wikipedia.org/wiki/Quine–McCluskey_algorithm

    Each bit in the binary string is used to represent the ticks within the prime implicant chart. The prime implicant chart can be created using the following steps: Iterate through each key (prime implicant of the dictionary). Replace each dash in the prime implicant with the \d character code. This creates a regular expression that can be ...
