WebI Rice’s theorem asserts that all \nontrivial" properties of Turing machines are undecidable. (To determine whether a given Turing machine’s language has property P is undecidable.) Theorem I Let P be a language consisting of TM descriptions such that 1. P is nontrivial-it contains some, but not all, TM descriptions. 2. WebTheory of Computation (With Formal Languages) This book has very simple and practical approach to make the understood the concept of automata theory and languages well.
