In this and the following question, consider those TMs that satisfy all of the following properties:Q={90,91,9a9r}: there are exactly two states besides the accept state and the reject state.• Σ={1}: the input alphabet has just one symbol.• [={1,_}: the tape alphabet has two symbols, where is the blank symbol.• The head is moved in every step, that is, 8 uses only L and R, but not N.• If the machine is started on the completely empty tape, it will halt after a finite number of steps, that is, it will reach qa or qr.If such a TM is started on the completely empty tape, it will leave a certain number of 1 symbols on the tape after it halts. What is the maximum number of 1 symbols on the tape, among all of these TMs?Answer:CheckConsider again the TMs of the preceding question. If such a TM is started on the completely empty tape, it will make a certain number of transition steps. What is the maximum number of steps, among all those TMs?Answer:Check

Let Σ={0,1}. Give a regular expression r over Σ such that L(r) = { w in Σ* | (w contains at least 2 symbols, that is, the length of w is at least 2) and (the first symbol of w is different from the last symbol of w) and (centre (w) is mimsy according to the following two definitions)}. For any string y containing at least 2 symbols, let centre (y) be the substring of y obtained by removing the first symbol and the last symbol of y. A string x over Σ is called mimsy if x is made up of either • at least two 0-symbols (and no 1-symbols), or an even number of 1-symbols (and no 0-symbols).
