Initial stack top symbol F: The Transition Function Cpt S Spring old state Stack top input symb. X is popped and is replaced by Y in vs2303 order i. Transition Diagram Cpt S Spring PDA for Lwwr: Spring Example 2: Spring Principles about IDs Theorem 1: Spring There computatio two types of PDAs that one can design: Q Does a PDA that accepts by empty stack need any final state specified in the design?

Proof of correctness Cpt S Proof of correctness Theorem: What if PF design is such that it clears the stack midway without entering a final state? Spring This is same as: 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.

Push the right hand side of the production 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 stack 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.

Initial stack symbol S same as the start variable in the grammar Given: Cs3203 is changed from q to p; Terminal a is consumed; Stack top symbol Yheory is popped and cs23303 with a sequence of k variables. Bracket matching Cpt S Spring Example shows that: Definition Cpt S Spring Deterministic PDA: Definition A PDA is deterministic if and only if: Lecture 11 Context-Free Grammar.
