PDAs are more powerful than FAs, being able to recognize languages that FAs cannot. In fact, the set of languages that can be recognized by PDAs are the context-free languages of the previous module.

WebTwo-way deterministic finite automaton. A two-way deterministic finite automaton (2DFA) is an abstract machine, a generalized version of the deterministic finite automaton (DFA) which can revisit characters already processed. As in a DFA, there are a finite number of states with transitions between them based on the current character, but each … WebDeterministic two-stack pushdown automaton is as powerful as Turing Machine.

"WebThe non-deterministic pushdown automata is very much similar to NFA. We will discuss some CFGs which accepts NPDA. The CFG which accepts deterministic PDA accepts non-deterministic PDAs as well. Similarly, there are some CFGs which can be accepted only by NPDA and not by DPDA. Thus NPDA is more powerful than DPDA. " - Deterministic pushdown automaton
