	Context-free grammar - Wikipedia, the free encyclopedia
		To prove that a given language is not context-free, one may employ the pumping lemma for context-free languages.
		A formal language is context-free if there is a context-free grammar that generates it.
		An alternative and equivalent definition of context-free languages employs non-deterministic push-down automata: a language is context-free if and only if it can be accepted by such an automaton.

	Context-free grammar - Wikipedia, the free encyclopedia
		For instance, given a context-free grammar, one can use the Chomsky Normal Form to construct a polynomial-time algorithm which decides whether a given string is in the language represented by that grammar or not (the CYK algorithm).
		Context-free grammars are powerful enough to describe the syntax of most programming languages; in fact, the syntax of most programming languages are specified using context-free grammars.
		On the other hand, context-free grammars are simple enough to allow the construction of efficient parsing algorithms which, for a given string, determine whether and how it can be generated from the grammar.
