Does a finite automata have memory

WebApr 25, 2024 · For automata with a finite memory and with $ n $ states the length of such a segment does not exceed $ n(n - 1)/2 $, and this maximum value is in fact attained for some automata. Automata with a finite memory are called self-regulating if, at a given time $ t $, the output letter at any moment $ \tau \geq t $ is independent of the initial state WebFinite-state machines are ideal computation models for a small amount of memory, and do not maintain memory. This mathematical model of a machine can only reach a finite …

A finite-state machine (FSM) or finite-state automaton (FSA, plural: automata), finite automaton, or simply a state machine, is a mathematical model of computation. It is an abstract machine that can be in exactly one of a finite number of states at any given time.

WebPushdown Automata A pushdown automaton (PDA) is a finite automaton equipped with a stack-based memory. Each transition is based on the current input symbol and the top of the stack, optionally pops the top of the stack, and optionally pushes new symbols onto the stack. Initially, the stack holds a special symbol Z 0 that indicates the bottom of the stack.
