Question
A Turing machine variant T' with the stay option for its head works
Turing machines except its head can stay at the current cell after the
the same as the standard
transition.
More formally, T' = (Q', ',I¹,8', s ,, f', r') where 8' : Q'×T' → Q'×T' x {L, R, S} with S
meaning the head stays at the current position after the transition. T' accepts an input string w
by entering f'.
Prove that this kind of Turing machine variants are equivalent to the standard Turing
machines.
