    Theorem — For any algorithms a 1 and a 2, at iteration step m (,,) = (,,), where denotes the ordered set of size of the cost values associated to input values , : is the function being optimized and (,,) is the conditional probability of obtaining a given sequence of cost values from algorithm run times on function .

  3. Interchange of limiting operations - Wikipedia

    Examples abound, one of the simplest being that for a double sequence a m,n: it is not necessarily the case that the operations of taking the limits as m → ∞ and as n → ∞ can be freely interchanged. [4] For example take a m,n = 2 m − n. in which taking the limit first with respect to n gives 0, and with respect to m gives ∞.

    That is, there is no real-valued representation of a preference relation by a utility function, whether continuous or not. [1] Lexicographic preferences are the classical example of rational preferences that are not representable by a utility function .

    Computers typically use binary arithmetic, but to make the example easier to read, it will be given in decimal. Suppose we are using six-digit decimal floating-point arithmetic , sum has attained the value 10000.0, and the next two values of input[i] are 3.14159 and 2.71828.

    An open compensation plan (or system or policy) is one with a defined pay scale and no rules about keeping employee pay confidential. Open compensation plans are noted for reducing employee turnover. One example of an organization with an open compensation system is the U.S. military.

    The cut-elimination theorem (or Gentzen's Hauptsatz) is the central result establishing the significance of the sequent calculus.It was originally proved by Gerhard Gentzen in part I of his landmark 1935 paper "Investigations in Logical Deduction" [1] for the systems LJ and LK formalising intuitionistic and classical logic respectively.
