 Embedded pushdown automaton

An **Embedded Pushdown Automaton (EPDA)** is a specific type of computational model that extends the capabilities of traditional pushdown automata (PDA). To understand what an EPDA is, it's helpful to first review some concepts related to pushdown automata. ### Pushdown Automaton (PDA) A **pushdown automaton** is a type of automaton that employs a stack as its primary data structure, allowing it to recognize a class of languages known as context-free languages.
