WebMay 21, 2024 · A context free grammar (CFG) is in Chomsky Normal Form (CNF) if all production rules satisfy one of the following conditions: A non-terminal generating two non-terminals (e.g.; X->YZ) The grammar G1 is in CNF as production rules satisfy the rules specified for CNF. WebA CFG (context free grammar) is in CNF (Chomsky normal form) if all production rules satisfy one of the following conditions: Start symbol generating ε. For example, A → ε.
