Push the right hand side of the production onto the stack, with leftmost symbol at the stack top If stack top lf 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 stack top has a terminal symbol, and if it matches with the next symbol in the input string, then pop it State notess inconsequential only one state is needed 25 March School of EECS, WSU.


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. What if PF design is such that it clears the stack midway without entering a final state?
