  2. Combinatory logic - Wikipedia

    en.wikipedia.org/wiki/Combinatory_logic

    Combinatory logic is a notation to eliminate the need for quantified variables in mathematical logic.It was introduced by Moses Schönfinkel [1] and Haskell Curry, [2] and has more recently been used in computer science as a theoretical model of computation and also as a basis for the design of functional programming languages.

  3. Fixed-point combinator - Wikipedia

    en.wikipedia.org/wiki/Fixed-point_combinator

    The type of the fixed point is the return type of the function being fixed. This may be a real or a function or any other type. In the untyped lambda calculus, the function to apply the fixed-point combinator to may be expressed using an encoding, like Church encoding. In this case particular lambda terms (which define functions) are considered ...

    The output function may be extended similarly into ¯ (,), which gives the complete output of the machine when run on word from state . Acceptor In order to study an automaton with the theory of formal languages , an automaton may be considered as an acceptor , replacing the output alphabet and function Γ {\displaystyle \Gamma } and λ ...

  5. Functional programming - Wikipedia

    en.wikipedia.org/wiki/Functional_programming

    The distinction between the two is subtle: "higher-order" describes a mathematical concept of functions that operate on other functions, while "first-class" is a computer science term for programming language entities that have no restriction on their use (thus first-class functions can appear anywhere in the program that other first-class ...

  6. Function object - Wikipedia

    en.wikipedia.org/wiki/Function_object

    In computer programming, a function object [a] is a construct allowing an object to be invoked or called as if it were an ordinary function, usually with the same syntax (a function parameter that can also be a function). In some languages, particularly C++, function objects are often called functors (not related to the functional programming ...

  9. Function (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Function_(computer...

    For example, a programmer may write a function in source code that is compiled to machine code that implements similar semantics. There is a callable unit in the source code and an associated one in the machine code, but they are different kinds of callable units – with different implications and features.
