Many of you asked why we couldn't have two stacks for PDAs? Now here comes a problem for you. It is natural to add an extra stack to a PDA Say M is a two-stack PDA if M is exactly the same as a PDA but with two stacks. Each instruction (transition) in M is in the form of which means that if M is at state q and reading input symbol a with the M to state p, and...

. Please design a standard TM (i.e., a single semi-infinite tape, deterministic) for the laın guage of all palindromes over alphabet {a, b} . Please give both the high-level description (text description or pseudo-code algorithm) and the low-level state transition diagram. Please analyze how many steps (one transition is considered as a step) it takes to accept an input palindrome with n symbols . Please design a deterministic Turing machine with two semi-infinite tapes for the same language. Please give...
(1) Turing Machine With left reset. ~Will Rate LifeSaver~
A Turing Machine with Left Reset is similar to an ordinary Turing Machine, but the transition function has the form:δ: Q x τ x {R,RESET}If δ(q,a) = {r,b,RESET} when the turing machine is in state q reading an a, the machine's head jumps to the left-hand end of the tape after it writes b on thetape and enters state r.Note that these machines do not have the usual ability to move the head one symbol left.Show that turing machines with...

1. Fill out the following blanks for the instructions of a Turing machine that would move an input string over (a, b) to the right one cell position. The tape head initially is at the left end of the input string. The rest of the tape cells are blank. The machine will move the entire string to the right one cell position and leave all remaining tape cells blank. The tape head ends at the right end of the output...

Consider the pushdown automaton with the following transition rules: 1.8(0,0,20) = {(q,XZ0)} 2. 8(9,0,X) = {(q,XX)} 3. 8(q,1,X) = {(q,x)} 4. 8(q,£,X) = {(p,ɛ)} 5. 8(p,£,X) = {(p,ɛ)} 6.8(p,1,X) = {(p,XX)} 7. 8(p,1,20) = {(p,ɛ)} From the ID (p,1101,XXZ0), which of the following ID's can NOT be reached?

1) Write a transition diagram for a Turing Machine that satisfies the following specifications. Do not make it skeletal -- show all possible transitions. (That means 3 transitions from each state (except the halt state) since Γ = {x, y, Δ} for this problem.) Pre: |Δ alpha Δ .... where alpha is a string of letters from {x,y} and ... are all Δ Post: if alpha is in the language described by regular expression (xy)* halt in the leftmost cell...
