It is always waiting for the next input symbol or making transitions. The PDA simulates the leftmost derivation on a given w, and upon consuming it fully it either arrives at acceptance by empty stack or non-acceptance.

Is w acceptable by the DFA?


Explicitly specifying dead states is just a matter of design convenience one that is generally followed in NFAsand this feature does not make a machine deterministic or non-deterministic. The Transition Function Cpt S Spring There are two types of PDAs that one can design: To make this website work, we log user data and share it with processors. Is w acceptable by the NFA?

Push the right hand side of the rheory onto the stack, with leftmost symbol at the stack top If stack top is the leftmost variable, then replace it by all its productions each possible substitution will represent a distinct path taken by the non-deterministic PDA If coomputation top has a terminal symbol, and if it matches with the next symbol in the input string, then pop it State is inconsequential only one state is needed 25 March School of EECS, WSU.
