    en.wikipedia.org/wiki/Help:Conditional_expressions

    Undefined parameter values are tricky: if the first positional parameter was not defined in the template call, then {{{1}}} will evaluate to the literal string "{{{1}}}" (i.e., the 7-character string containing three sets of curly braces around the number 1), which is a true value.

  3. P versus NP problem - Wikipedia

    en.wikipedia.org/wiki/P_versus_NP_problem

    The P versus NP problem is a major unsolved problem in theoretical computer science.Informally, it asks whether every problem whose solution can be quickly verified can also be quickly solved.

  4. Equality (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Equality_(mathematics)

    The equals sign, used to represent equality symbolically in an equation. In mathematics, equality is a relationship between two quantities or expressions, stating that they have the same value, or represent the same mathematical object. [1] [2] Equality between A and B is written A = B, and pronounced "A equals B".

    en.wikipedia.org/wiki/Cycle_detection

    Let S be any finite set, f be any endofunction from S to itself, and x 0 be any element of S.For any i > 0, let x i = f(x i − 1).Let μ be the smallest index such that the value x μ reappears infinitely often within the sequence of values x i, and let λ (the loop length) be the smallest positive integer such that x μ = x λ + μ.

    That is, for any two random variables X 1, X 2, both have the same probability distribution if and only if =. [citation needed] If a random variable X has moments up to k-th order, then the characteristic function φ X is k times continuously differentiable on the entire real line.

  7. Boolean data type - Wikipedia

    en.wikipedia.org/wiki/Boolean_data_type

    The C programming language uses an integer type, where relational expressions like i > j and logical expressions connected by && and || are defined to have value 1 if true and 0 if false, whereas the test parts of if, while, for, etc., treat any non-zero value as true. [1] [2] Indeed, a Boolean variable may be regarded (and implemented) as a ...

    en.wikipedia.org/wiki/Sylvester_matrix

    the second row is the first row, shifted one column to the right; the first element of the row is zero. the following n − 2 rows are obtained the same way, shifting the coefficients one column to the right each time and setting the other entries in the row to be 0. if m > 0 the (n + 1)th row is:

  9. Hölder condition - Wikipedia

    This also includes β = 1 and therefore all Lipschitz continuous functions on a bounded set are also C 0,α Hölder continuous. The function f(x) = x β (with β ≤ 1) defined on [0, 1] serves as a prototypical example of a function that is C 0,α Hölder continuous for 0 < α ≤ β, but not for α > β.
