S) Is In Normal Form If And Only If R Contains No Rules Of The Form.

Also, note that grammars are by definition finite: A grammar might describe infinitely many strings, but. I your first grammar, you can derive epsilon from s. Web chomsky normal form complexity.

Web A Context Free Grammar (Cfg) Is In Chomsky Normal Form (Cnf) If All Production Rules Satisfy One Of The Following Conditions:

(all tokens must be separated by space characters). A → bc, or a → a, or s → ε, where a, b, and c are nonterminal symbols, the letter a is a terminal symbol (a symbol that represents a constant value), s is the start symbol, and ε denotes the empty string. So the empty word belong to the described language. Therefore you must have a epsilon in the second.
