  2. Gaussian elimination - Wikipedia

    en.wikipedia.org/wiki/Gaussian_elimination

    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. This method can also be used to compute the rank of a matrix, the determinant of a square matrix, and the inverse of ...

  3. Sequential elimination method - Wikipedia

    en.wikipedia.org/wiki/Sequential_elimination_method

    v. t. e. The sequential elimination methods are a class of voting systems that repeatedly eliminate the last-place finisher of another voting method until a single candidate remains. [1] The method used to determine the loser is called the base method. Common are the two-round system, instant-runoff voting, and systems where parties nominate ...

  4. Instant-runoff voting - Wikipedia

    en.wikipedia.org/wiki/Instant-runoff_voting

    Instant-runoff voting (IRV), also known as ranked-choice voting (RCV), preferential voting (PV), or the alternative vote (AV), [1] is a multi-round elimination method where the loser of each round is determined by the first-past-the-post method. [2][3] In academic contexts, the term instant-runoff voting is generally preferred as it does not ...

    en.wikipedia.org/wiki/Modus_ponens

    In propositional logic, modus ponens (/ ˈ m oʊ d ə s ˈ p oʊ n ɛ n z /; MP), also known as modus ponendo ponens (from Latin 'method of putting by placing'), [1] implication elimination, or affirming the antecedent, [2] is a deductive argument form and rule of inference. [3] It can be summarized as "P implies Q. P is true. Therefore, Q must ...

    Construction of network flow for baseball elimination problem. In the baseball elimination problem there are n teams competing in a league. At a specific stage of the league season, w i is the number of wins and r i is the number of games left to play for team i and r ij is the number of games left against team j. A team is eliminated if it has ...

  7. Elimination theory - Wikipedia

    en.wikipedia.org/wiki/Elimination_theory

    Elimination theory. In commutative algebra and algebraic geometry, elimination theory is the classical name for algorithmic approaches to eliminating some variables between polynomials of several variables, in order to solve systems of polynomial equations. Classical elimination theory culminated with the work of Francis Macaulay on ...

  8. Penalty method - Wikipedia

    en.wikipedia.org/wiki/Penalty_method

    Penalty methods are a certain class of algorithms for solving constrained optimization problems. A penalty method replaces a constrained optimization problem by a series of unconstrained problems whose solutions ideally converge to the solution of the original constrained problem. The unconstrained problems are formed by adding a term, called a ...

    Zaytsev's rule. In organic chemistry, Zaytsev's rule (or Zaitsev's rule, Saytzeff's rule, Saytzev's rule) is an empirical rule for predicting the favored alkene product (s) in elimination reactions. While at the University of Kazan, Russian chemist Alexander Zaytsev studied a variety of different elimination reactions and observed a general ...
