WebSep 19, 2012 · Pumping Lemma. Suppose L is context free. By the pumping lemma, there is a length p (not necessarily the same p as above) such that any string w in L can be represented as uvxyz, where. vxy <= p, vy >= 1, and. u v i x y i z is in L for i >= 0. Given a string w in L, either m > n or m < n. Suppose p = 2. Suppose that m > n.

WebNov 5, 2015 · One way of determining whether a given context-free grammar G produces an infinite language is this: Find a grammar G + with L ( G +) = L ( G) such that G ′ has no rules on the form A → ε or A → B where A and B are any non-terminals. (Implication: for any derivation α A _ β ⇒ α γ β we have α A β < α γ β unless γ is a single terminal.) WebDec 13, 2015 · The complement of a context-free language can be context-free or not; the complement of a non-context free language can be context-free or not.
