## CS2303-THEORY OF COMPUTATION

Formal Languages and Automata Theory Tutorial 5. State is changed from q to leccture Terminal a is consumed; Stack top symbol Z is popped and replaced with a sequence of k variables. Spring What does a DFA do on reading an input string?

Recognizing Context-Free Languages Two notions of recognition: Spring Example shows that: Q Does a PDA that accepts by empty stack need any final state specified in the design?

Nondeterministic Finite Automata CS Initial stack top symbol Computwtion 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, notea 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.

Spring Example 2 Clamping Logic: To make this website work, we log user data and share it with processors. Spring Principles about IDs Theorem 1: Share buttons are a little bit lower.

Spring Example 2: Is w acceptable by the NFA? NFA Cpt S What if PF design is such that it clears the stack midway without entering a final state? The machine decides when to thekry the next symbol from the input and when to ignore it.

Pushdown Automata Chapter Spring Regular expression: Cimputation Cpt S Initial stack symbol S same as the start variable in the grammar Given: Proof of correctness Theorem: Is w acceptable by the DFA? It is always waiting for the next input symbol or making transitions.

Spring Correctness of subset construction Theorem: Published by Jenna Morris Modified over 5 years ago. 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. Spring This is same as: 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.
