Automata - Nondeterministic automata (NFA)

Card Puncher Data Processing

About

Nondeterministic finite automata (NFA) is a finite automata that can be in several states at once (several variable)

The inverse of Nondeterministic automata (NFA) is deterministic finite-state automata (DFA) that cannot be in more than one state at any one time.

Application

Nondeterminism allows to program solutions to problems using a higher-level language.

The nondetemministic finite automaton is then compiled into a deterministic automaton.
