WebMar 24, 2015 · Anchor: After processing the only string of length zero, ε, the automaton is in state q 0 as claimed. Hypothesis: After reading a string u the automaton is in state q 1 iff u = x a, and in state q 2 iff u = x a b and in q 0 iff u = ε or u = x b. The claim holds for input fragments of length up to n. Step: Any string v of length n + 1 is ... WebDeterministic Finite Automata (DFA) We now begin the machine view of processing a string over alphabet Σ. The machine has a semi-infinite tape of squares holding one alphabet symbol per square. The machine has a finite state set, K, with a known start state. Initially we want the processing to be deterministic, that is, there is only one ...
