Que-3: Draw a deterministic and non-deterministic finite automata which accept a string containing “ing” at the end of a string in a string of {a-z}, e.g., “anything” but not “anywhere”. It is applicable for all the DFA and NFA. In final state acceptability, a PDA accepts a string when, after reading the entire string, the PDA is in a final state. Advertisements.

Section 3.3 Fri, Oct 21, 2005 Push-Down Automata Recall that DFAs accept regular languages. In par- ticular, after formally introducing push-down automata in Section 14.1, we introduce two notions of acceptance - by final state and by empty stack - in Sections 14.1.2 and 14.1.3, respectively. In the case of deterministic nite automata, problems like equivalence can be solved even in polynomial time. Pushdown-automata are recognizing mechanisms, i.e., a PDA recognizes a context-free languiage. • Pushdown Automata • definitions, examples, equivalence with context-free grammars • Non-Context-Free Languages • the pumping lemma for context-free languages Theory of Computation, Feodor F.
