(a) Turing Machines can easily be designed to recognize regular languages. Construct either a Turing Machine that accepts the language denoted by the regular expression 0^*1 for the alphabet Σ = {0, 1}. Choose a random string in the language and trace through it (step by step) using your machine

please answer a,b, and c Consider the following Turing Machine. M = “On input hA,Bi where A and B are DFAs: 1. Iterate through strings in Σ∗ in shortlex order; where Σ represents the common symbols of their input alphabets. For each string iterated, simulate both A and B on it. 2. If a string is ever encountered that both A and B accept, then accept.” (a) (2 points) Give a description, in English, of the language that M recognizes....

determine if the language is regular, context-free, Turing-decidable, or undecidable. For languages that are regular, give a DFA that accepts the language, a regular expression that generates the language, and a maximal list of strings that are pairwise distinguishable with respect to the language. For languages that are context-free but not regular, prove that the language is not regular and either give a context- free grammar that generates the language or a pushdown automaton that accepts the language. You need...

A Turing machine that halts on all inputs is called a halting Turing machine (also known as Decider). Prove the following: (a) If M1 and M2 are two halting Turing machines, then there exists a halting Turing machine that recognizes L(M1) ∩ L(M2). (b) If M1 and M2 are two (not necessarily halting) Turing machines, then there exists a Turing machine that recognizes L(M1) ∩ L(M2).
