Web7. NPDA's and general NFA's may not halt for finite inputs like DFA's do because of their ϵ transitions. However, NFA's with ϵ transitions could be converted to those without any ϵ transitions and hence they can be made to halt. I was wondering if this is possible even for the case of NPDA's. Is there a canonical epsilon-free form for PDAs. WebJul 6, 2024 · Definition 4.4. A pushdown automaton M is specified by six components M = (Q, Σ, Λ, q0, ∂, F) where. Q is a finite set of states.
