• ω-automaton — In automata theory, a branch of theoretical computer science, an ω automaton (or stream automaton) is a deterministic or nondeterministic automaton that runs on infinite, rather than finite, strings as input. Since ω automata do not stop, they… …   Wikipedia

• Büchi automaton — A Büchi automaton is the extension of a finite state automaton to infinite inputs. It accepts an infinite input sequence iff there exists a run of the automaton (in case of a deterministic automaton, there is exactly one possible run) which… …   Wikipedia

• Deterministic pushdown automaton — In automata theory, a pushdown automaton is a finite automaton with an additional stack of symbols; its transitions can take the top symbol on the stack and depend on its value, and they can add new top symbols to the stack. A deterministic… …   Wikipedia

• Pushdown automaton — In automata theory, a pushdown automaton (PDA) is a finite automaton that can make use of a stack containing data. Operation Pushdown automata differ from normal finite state machines in two ways: # They can use the top of the stack to decide… …   Wikipedia
