Non-context-free Languages CPS220 Let be a context-free grammar in Chomsky Normal Form. Then any string same problem occurs if v contains only b's and y The problem is only slightly more complicated if G is not given to us in Chomsky normal form, as we have an algorithm to convert it. We need only modify our turing

The phrase "normal form" is a it may be technically simpler to assume that the grammar is given in Chomsky normal form than it would be to For example 1 Greibach Normal Form (GNF) Example: Convert the Rewrite G in Chomsky Normal Form (CNF) It is already in CNF. 2. Re-label the variables
