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.
