A Review Paper on Pushdown Automata Implementation

In the theory of computation, a branch of theoretical computer science, a pushdown automaton (PDA) is a type of automaton that employs a stack. Pushdown automata are used in theories about what can be computed by machines. They are more capable than finite-state machines but less capable than Turing machines (see below).

"WebIn a nutshell: This idea that a non-deterministic automaton can guess (or be helped by an oracle) is directly related to our existential interpretation of non-determinism. Another interpretation is possible (maybe others) where "guessing" would not make sense. Non determinism is strange. " - Deterministic pushdown automaton
