Define a reset Turing machine to be a variant that moves the head by either: (i) keeping the head in the same location, (ii) moving the head to right, or (iii) resetting the head to the first cell on the tape. (Otherwise, the variant is defined identically to the standard Truing machine model.) Prove a language L is Turing recognizable iff it can be recognized by a reset Turing machine. In particular, if M is the Turing machine that recognizes L, show how it is possible to construct a reset Turing machine M' that also recognizes L.

Define a reset Turing machine to be a variant that moves the head
by either: (i) keeping the head in the same location, (ii) moving the head to right, or (iii)
resetting the head to the first cell on the tape. (Otherwise, the variant is defined identically
to the standard Truing machine model.)
Prove a language L is Turing recognizable iff it can be recognized by a reset Turing machine.
In particular, if M is the Turing machine that recognizes L, show how it is possible to
construct a reset Turing machine M' that also recognizes L.
