Is context-free grammar deterministic?
In formal grammar theory, the deterministic context-free grammars (DCFGs) are a proper subset of the context-free grammars.
They are the subset of context-free grammars that can be derived from deterministic pushdown automata, and they generate the deterministic context-free languages.
What is DCFL and DPDA?
DCFL = {L(M) : M is a DPDA}, where DCFL is the set of deterministic context free languages and DPDA stands for deterministic pushdown automaton.
Here are some facts about DCFL: .
1) DCFL is closed under complementation. .
2) DCFL is not closed under union, and not closed under intersection.
What is an example of a deterministic language?
An example of linguistic determinism is how the Turkish language has two different past tenses: one to express personal knowledge of an event and another to express a more passive knowledge.
Linguistic relativity is the theory that languages influence how humans think and interact with the world.
CFL are closed under union, but not under complement.
DCFL are not closed under union, but closed under complement.
The undecidability of regularity for CFL is usually obtained from two properties of the context-free languages: (1) they are closed under union, and (2) universality, i.e., equality to Σ∗, is undecidable.

In formal language theory, deterministic context-free languages (DCFL) are a proper subset of context-free languages. They are the context-free languages that can be accepted by a deterministic pushdown automaton. DCFLs are always unambiguous, meaning that they admit an unambiguous grammar.
