What is finite automata with example?
A finite automaton (FA) is a simple idealized machine used to recognize patterns within input taken from some character set (or alphabet) C. The job of an FA is to accept or reject an input depending on whether the pattern defined by the FA occurs in the input. A finite automaton consists of: a finite set S of N states.What is a real life example of finite automata?
An automatic door is a good example of finite automata. It is sensing a person's appearance and accordingly open & close the door. It has two states OPEN and CLOSE and the controller works on the input signals.What are 3 examples of automata?
Automatic photo printing machines, artificial card punching machines, human detection, and reorganization machine, etc. are real time examples of automata.- The finite automaton starts in state q0 and reads the characters of its input string one at a time. If the automaton is in state q and reads input character a, it moves from state q to state ? (q, a). Whenever its current state q is a member of A, the machine M has accepted the string read so far.
