Write short notes on recursive and recursively enumerable language Write short notes on NP hard and NP complete problems Discuss any two undecidable problems about the Turing machine Explain the difference between P and NP problems Discuss the decidability of Posts correspondence problem Explain any two NP complete problems If L1 and L2 are recursive languages then L1 U L2 is a recursive language Prove that the halting problem is undecidable State and prove the Posts correspondence problem Write a note on NP problem Explain about A language that is not Recursively Enumerable Prove Lne is recursively enumerable Discuss on undecidable problem about Turing Machine Explain about the PCP but not recursive.

State and prove Rices theorem for recursively enumerable index sets Consider the language of all TMs that gives no input eventually writes a non blank symbol on their tapes. Explain why this set is decidable. Why does this non conflict with the halting problem 2. Prove that the Post Correspondence Problem is decidable for strings over the alphabets Prove that the problem of determining if the language generated by two CFGs are equal id undecidable.

Sipser writes clearly and explains concepts well but, crucially, he does an incredible job building up your intuition. You don't just learn the material, you understand it. That's something few authors try and fewer yet delive The best textbook I've read on any subject—by some margin.

That's something few authors try and fewer yet deliver. The most visible component of this is the book's structure with "proof sketches"—little proof roadmaps—laid out before diving into the fiddly details of the full proof.

All too often, proofs jump around in surprising ways—sure, approach X works, but where did it come from? What insight is it based on? Proof sketches, coupled with quality prose, help you understand where proofs come from and why they make sense, not just how they work.

He also introduces some interesting context to the ideas and formalisms presented. His observation on the "robustness" of Turing-completeness—how virtually any reasonable model of computation, however weird and exotic, seems to have the same level of power—still influences my views on math and CS. Robust properties, emerging almost on their own, make mathematical ideas seem far less arbitrary than they would otherwise.
