Given a Turing machine M one can construct a Context-free grammar whose language is either Σ ∗ or Σ ∗ − w depending on whether M halts. These are both regular languages and so if we could exhibit a regular grammar we could decide the halting problem. WebA context-free grammar is a notation for describing languages.
