The Finite State Machine is the component of the AAA Server software that controls the flow of access request authentication and accounting request handling, abbreviated as FSM.
a collection of machine states S, input values I and response values R, along with two transition functions F and G
a conceptual machine that works by performing some action in response to an external event
a device, or a model of a device, which has a finite number of states it can be in at any given time and can operate on input to either make transitions from one state to another or to cause an output or action to take place
a digital circuit whose output is dependent not only on its input but on its previous input, i
a machine that given an input, jumps through a series of states according to a transition function (can be seen as a table) that tells the automaton which state to go next given a current state and a current symbol
a model of behavior composed of states, transitions and actions
an abstract machine formalism composed of nodes ( state s) and arcs ( state transitions or operations)
an abstract system which can exist in any of a discrete set of states or conditions, with the state at any instant characterized by the collective state of all of the individual cells which comprise the machine
an imaginary (or abstract) machine that is used to study and design systems that recognize and identify patterns
A machine with a fixed number of internal options or possibilities. These could be as few as 2 (Yes/No) or any number of separate possibilities, each determined by some combination of input parameters.
A computer, or operating system, in which a set of inputs determine not only the set of outputs but also the internal state of a computer, so that processing is optimized.
A mathematical model of an entity that describes its behavior as a result of its past history and current inputs. If an example entity is a customer, inputs might be direct mail promotions and responses could be a purchase or changed loyalty score.
A knowledge representation that makes different states in a process explicit, and connects them with links that specify some transition condition that specifies how one traverses from one state to another.
A device that takes inputs and looks up appropriate outputs from an internal table in a manner dependent on the machine's internal state. The internal state permits the machine to look up different outputs depending on the history thus far. This internal state is thus a form of memory. The outputs may either be associated with the transitions to a next state or may be associated with the states themselves. These two different types of finite state machines are called Mealy and Moore machines, respectively.
Finite state machines (FSM's) are machines (generally computer programs) which proceed in clearly separate and discrete steps from one to another of a finite number of configurations or states. There is a well-known relationship between classes of language grammars and finite state machines, namely, that finite state machines are capable of recognizing regular grammars. Regular grammars describe the simplest languages (in Chomsky's types) and are suitable for linguistic tasks such as stemming, spell checking, and many other operations.
