Example text

Beginning with the second column of the table, we associate a column to each letter of the alphabet Σ. If the first element of the ith row is (q, q ) then at the cross of ith row and the column associated to letter a will be the pair elem δ(q, a) , elem δ (q , a) . a ... ... (q, q ) elem δ(q, a) , elem δ (q , a) ... 2. Finite automata and regular languages 35 In the first column of the first row we put (q0 , q0 ) and complete the first row using the above method. If in the first row in any column there occur a pair of states from which one is a final state and the other not then the algorithm ends, the two automata are not equivalent.

We show that |u| < n. If |u| ≥ n, then we apply the pumping lemma, and give the decomposition u = xyz, |y| > 1 and xz ∈ L. This is a contradiction, because |xz| < |u| and u is the shortest word in L. Therefore |u| < n. 17 There exists an algorithm that can decide if a regular language is or not empty. Proof Assume that L = L(A), where A = (Q, Σ, E, {q0 }, F ) is a DFA. 15 language L is not empty if and only if it contains a word shorter than n, where n is the number of states of automaton A. By this it is enough to decide that there is a word shorter than n which is accepted by automaton A.

31). The pushdown automaton get a word as input, start to function from an initial state having in the stack a special symbol, the initial stack symbol. 3. Pushdown automata and context-free languages 61 (or empty word) and stack top symbol and replace the top symbol in the stack with a (possibly empty) word. There are two type of acceptances. The pushdown automaton accepts a word by final state when after reading it the automaton enter a final state. The pushdown automaton accepts a word by empty stack when after reading it the automaton empties its stack.
