• Nondeterministic finite-state machine — In the theory of computation, a nondeterministic finite state machine or nondeterministic finite automaton (NFA) is a finite state machine where for each pair of state and input symbol there may be several possible next states. This distinguishes …   Wikipedia

• Alternating finite automaton — In automata theory, an alternating finite automaton (AFA) is a nondeterministic finite automaton whose transitions are divided into existential and universal transitions. For example, let A be an alternating automaton.* For an existential… …   Wikipedia

• Generalized nondeterministic finite state machine — In the theory of computation, a generalized nondeterministic finite state machine or generalized nondeterministic finite automaton (GNFA) is a NFA where each transition may be labeled with any regular expression. The GNFA reads blocks of symbols… …   Wikipedia

• Finite state machine — A finite state machine (FSM) or finite state automaton (plural: automata ) or simply a state machine, is a model of behavior composed of a finite number of states, transitions between those states, and actions. A finite state machine is an… …   Wikipedia

• Finite state transducer — A finite state transducer (FST) is a finite state machine with two tapes: an input tape and an output tape. This contrasts with an ordinary finite state automaton (or finite state acceptor), which has a single tape. OverviewAn automaton can be… …   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

• 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

• Complementation of Büchi automaton — In automata theory, complementation of a Büchi automaton is construction of another Büchi automaton that recognizes complement of the ω regular language recognized by the given Büchi automaton.
