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 …

Deterministic PDA’s To be deterministic, there must be at most one choice of move for any state q, input symbol a, and stack symbol X. In automata theory, a deterministic pushdown automaton (DPDA or DPA) is a variation of the pushdown automaton. The class of deterministic pushdown automata accepts the deterministic context-free languages, a proper subset of context-free languages. Machine transitions are based on the … See more A (not necessarily deterministic) PDA $${\displaystyle M}$$ can be defined as a 7-tuple: $${\displaystyle M=(Q\,,\Sigma \,,\Gamma \,,q_{0}\,,Z_{0}\,,A\,,\delta \,)}$$ where See more • Hamburger, Henry; Dana S.
