A deterministic context-free language is a formal language which is defined by a deterministic context-free grammar. The set of deterministic context-free languages is called DCFL and is identical to the set of languages accepted by a deterministic pushdown automaton.
The set of deterministic context-free languages are a proper subset of the set of context-free languages that possess an unambiguous context free grammar. For example, the language ...
