WebMar 28, 2024 · The definition that my teacher told me about CNF: It is a context-free language whose productions are from two types: Type 1: $A \rightarrow a\ \ A \in N,\ a \in \Sigma$ Type 2: $A \rightarrow BC\ \ A,B,C \in N$ Nothing less and nothing more. You can always simplify a CFL but that is not necessary. At least from a theoretical point of view. hxy twitch
