PPT-1 Introduction to Computability Theory

Lecture2 Non Deterministic Finite Automata cont Prof Amos Israeli Roadmap for Lecture In this lecture we Prove that NFAs and DFAs are equivalent Present the three regular operations. More precisely we can explain what it means for a partial arith metic function to be computable Since we can code any 64257nite discrete object as a natural number in a natural way we also have a notion of computability on these obj ects We can use C Berkeley CS172 Automata Computability and Complexity Solutions to Problem Set 4 Professor Luca Trevisan 2232007 Solutions to Problem Set 4 1 Sipser Problem 313 A Turing machine with stay put instead of le Outline We simply determine if is the same as its reversal language This works because the reverse of the implication in the de64257nition of must also be true for any machine in by reversing twice Proof Consider a TM which on input does the follo Lecture5: Context .

There are many alternative definitions of Turing machines. Those are called . variants . of the original Turing machine. Among the variants are machines with many tapes and non deterministic machines. . Sigmund Freud is the father of psychoanalysis.
