WebJan 4, 2024 · Abstract. Pushdown automata (PDAs) can be thought of as combining an NFA “control-unit” with a “memory” in the form of an infinite stack. 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.
