Theory of Computation Playlist:    • Theory of Computation | Automata Theory | ...   Chomsky Normal Form: A Context-Free Grammar G is in Chomsky Normal Form(CNF) if all productions are of the form X → YZ or X → a. Some Important Results about CNF (Explained with Proof): Let G be a CFG in Chomsky Normal Form, & w in L(G) with |w| = n . 1. EVERY derivation of string w contains Exactly 2n-1 steps.  (NOTE: Every leftmost derivation, every rightmost derivation, every other derivation, EACH derivation of string $w$ contains Exactly 2n-1 steps. ) 2. The Parse Trees (Derivation Tress) of strings generated by a CNF grammar are Always Binary Trees. 3. EVERY Parse Tree of string $w$ has Exactly 2n-1 Internal Nodes, Exactly 3n-1 total nodes. (If CNF grammar is Ambiguous, w may have more than 1 parse trees, & EACH parse tree will have exactly 2n-1 internal nodes, exactly 3n-1 total nodes.)

Some Important Results about GNF (Explained with Proof): Let G be a CFG in Greibach Normal Form, & w in L(G) with |w| = n. 1. EVERY derivation of string w contains Exactly n steps.  (NOTE: Every leftmost derivation, every rightmost derivation, every other derivation, EACH derivation of string w contains Exactly n steps. ) 2. The Parse Trees (Derivation Tress) of strings generated by a GNF grammar may not be binary trees. 3. EVERY Parse Tree of string w has Exactly n Internal Nodes, Exactly 2n total nodes. (If GNF grammar is Ambiguous, w may have more than 1 parse trees, & EACH parse tree will have exactly n internal nodes, exactly 2n total nodes.)
