"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
