deterministic automaton

(theory)
A finite-state automaton in which the overall course of the computation is completely determined by the program, the starting state, and the initial inputs. The class of problems solvable by such automata is the class P (see polynomial-time algorithm).

Deterministic Automaton

 

a mathematical model of a system whose states change discretely with time in such a way that every state of the system is completely defined by the previous state and the input signal. A deterministic automaton is formally described in the form of the function f(Si, aj) = ak, where si is the input signal and aj is the previous state. A typical example of a deterministic automation is a digital computer, in which the state of all registers and cells is determined by their previous state and by the input signals. Deterministic automatons are a natural form for describing the logical structure of discrete computing devices. Conversion to nondeterministic automatons is possible both by the introduction of the probabilities of a change of states and by the free selection of the next state.
