Question: Consider a simple polycephalic Turing machine which has two tapes, i 1 and i 2 , each of which is filled completely by zero's except

Consider a simple "polycephalic" Turing machine which has two tapes, i₁ and i₂, each of which is filled completely by zero's except for a single block of 1's. Let the blocks of 1's on the two tapes be right-justified, as indicated above. Find the simplest possible next-move function that will enable an outside observer to determine whether or not the number of 1's on tape i₁ is greater than or equal to the number of 1's on tape i₂, assuming that he cannot observe the state q of the Turing machine.
