5. CF Pumping Lemma, Turing Machines
Turing Machines and Context Free Languages. Context Free languages (CFLs) are languages that are recognised by Context Free Grammars, i.e., grammars. A finite-state machine has the same computational power as a Turing machine that is restricted such that its head may only perform "read" operations, and always. Finite state automata can be used to recognize only regular languages. To recognize a context-free grammar, we need to use a pushdown automaton. This is a.
