  2. Moore machine - Wikipedia

    en.wikipedia.org/wiki/Moore_machine

    As Moore and Mealy machines are both types of finite-state machines, they are equally expressive: either type can be used to parse a regular language.. The difference between Moore machines and Mealy machines is that in the latter, the output of a transition is determined by the combination of current state and current input (as the domain of ), as opposed to just the current state (as the ...

  3. Finite-state machine - Wikipedia

    en.wikipedia.org/wiki/Finite-state_machine

    An FSM is defined by a list of its states, its initial state, and the inputs that trigger each transition. Finite-state machines are of two types—deterministic finite-state machines and non-deterministic finite-state machines. [2] For any non-deterministic finite-state machine, an equivalent deterministic one can be constructed.

  4. Mealy machine - Wikipedia

    en.wikipedia.org/wiki/Mealy_machine

    The state diagram for a Mealy machine associates an output value with each transition edge, in contrast to the state diagram for a Moore machine, which associates an output value with each state. When the input and output alphabet are both Σ , one can also associate to a Mealy automata a Helix directed graph [ clarification needed ] ( S × Σ ...

  5. Algorithmic state machine - Wikipedia

    en.wikipedia.org/wiki/Algorithmic_State_Machine

    An ASM chart consists of an interconnection of four types of basic elements: state name, state box, decision box, and conditional outputs box. An ASM state, represented as a rectangle, corresponds to one state of a regular state diagram or finite-state machine. The Moore type outputs are listed inside the box. State Name

  6. State diagram - Wikipedia

    en.wikipedia.org/wiki/State_diagram

    A state diagram for a door that can only be opened and closed. A state diagram is used in computer science and related fields to describe the behavior of systems. State diagrams require that the system is composed of a finite number of states. Sometimes, this is indeed the case, while at other times this is a reasonable abstraction.

  7. State-transition table - Wikipedia

    en.wikipedia.org/wiki/State-transition_table

    In the state-transition table, all possible inputs to the finite-state machine are enumerated across the columns of the table, while all possible states are enumerated across the rows. If the machine is in the state S 1 (the first row) and receives an input of 1 (second column), the machine will stay in the state S 1 .

  8. Automata theory - Wikipedia

    en.wikipedia.org/wiki/Automata_theory

    An automaton with a finite number of states is called a finite automaton (FA) or finite-state machine (FSM). The figure on the right illustrates a finite-state machine, which is a well-known type of automaton. This automaton consists of states (represented in the figure by circles) and transitions (represented by arrows).

  9. UML state machine - Wikipedia

    en.wikipedia.org/wiki/UML_state_machine

    The pattern of events, states, and state transitions among those states can be abstracted and represented as a finite-state machine (FSM). The concept of a FSM is important in event-driven programming because it makes the event handling explicitly dependent on both the event-type and on the state of the system.
