science, a recursive (or decidable) language is a recursive subset of the Kleene closure of an alphabet. Equivalently, a formal language is recursive if there...

In mathematics, logic and computer science, a formal language is called recursively enumerable (also recognizable, partially decidable, semidecidable,...

explained as the consequence of recursion in natural language. This can be understood in terms of a recursive definition of a syntactic category, such as a sentence...

recursive elements of language such as spatial prepositions. Then this merged with their parents' non-recursive language to create recursive language...

In computability theory, a primitive recursive function is, roughly speaking, a function that can be computed by a computer program whose loops are all...

function 1 S {\displaystyle \mathbb {1} _{S}} is computable. Every recursive language is a computable. Every finite or cofinite subset of the natural numbers...

repeatedly call code. It is proved in computability theory that these recursive-only languages are Turing complete; this means that they are as powerful (they...

Formal Languages by A. Salomaa, page 14, Example 2.5). An example of recursive language that is not context-sensitive is any recursive language whose decision...

A recursive acronym is an acronym that refers to itself, and appears most frequently in computer programming. The term was first used in print in 1979...

every context-free language is context-sensitive, every context-sensitive language is recursive and every recursive language is recursively enumerable. These...

computer science, a recursive descent parser is a kind of top-down parser built from a set of mutually recursive procedures (or a non-recursive equivalent) where...

A recursive island or lake, also known as a nested island or lake, is an island or a lake that lies within a lake or an island. For the purposes of defining...

Recursive self-improvement (RSI) is a process in which an early or weak artificial general intelligence (AGI) system enhances its own capabilities and...

target of a tail is the same subroutine, the subroutine is said to be tail recursive, which is a special case of direct recursion. Tail recursion (or tail-end...

Scheme is a statically scoped and properly tail-recursive dialect of the Lisp programming language invented by Guy L. Steele, Jr. and Gerald Jay Sussman...

LOOP is a simple register language that precisely captures the primitive recursive functions. The language is derived from the counter-machine model. Like...

an undecidable problem is a problem whose language is not a recursive set; see the article Decidable language. There are uncountably many undecidable problems...

Otherwise it is called a non-recursive grammar. For example, a grammar for a context-free language is left recursive if there exists a non-terminal...

fac (n : int) : int = n * fac (n - 1) This describes the factorial as a recursive function, with a single terminating base case. It is similar to the descriptions...

The Syntax/Semantic Language (S/SL) is an executable high level specification language for recursive descent parsers, semantic analyzers and code generators...

earlier, but unrelated, programming language that Thompson designed for use on Multics. B was designed for recursive, non-numeric, machine-independent applications...

exploits similarities between these two languages, in part because of their dynamic typing and their simple, recursive data structures. This combination is...
