please explain Transitions that read a character off the
input are very tiresome, so we want to allow \"breaks\"
between them. I want every accepting computation of
every string to consist of at least 1 transition between
each character read from the input (I\'m not worried about
what happens on the stack here). Call these machines
HPDAs. What is the relation between the class of
languages PDAs recognize and those that HPDAs
recognize? They are exactly the same. They have no
languages in common. Every language a PDA recognizes,
a HPDA also recognizes, but not vice versa. Every
language a HPDA recognizes, a PDA also recognizes, but
not vice versa. There are languages in common, but some
languages a PDA can recognize and a HPDA cannot, and
vice versa.
Solution
Answer:
Because HPDA is generalization of PDA , every PDA can be
converted or we can say that simulated to PDA but the
converse doesn not hold . That is whty there might be the
chances that PDA can recognise but HPDA can not.
