![]() They are more capable than finite-state machines but less capable than Turing machines (see below).ĭeterministic pushdown automata can recognize all deterministic context-free languages while nondeterministic ones can recognize all context-free languages, with the former often used in parser design. Pushdown automata are used in theories about what can be computed by machines. ![]() In the theory of computation, a branch of theoretical computer science, a pushdown automaton ( PDA) isĪ type of automaton that employs a stack.
