WebOct 30, 2024 · So we add A → a to replace T → a a by T → A A. In the same way we add B → b and turn T → b b into T → B B and turn T → b T b into T → B T B. Lastly, we must pull apart T → B T B again. To do that, just add C → B T and replace T → B T B with T → C B. The CNF we're left with finally is: S ′ → S. S → T ′ S T S a.
