WebTheorem: Let M be a k-tape Turing machine for some k ≥ 1. Then there is a standard Turing machine M' where Σ ⊆ Σ', and such that: • For any input string x, M on input x halts with output y on the first tape iff M' on input x halts at the same halting state and with the same output on its tape.

WebMay 29, 2024 · Indeed, this is a practical version of the Turing Machine: that abstract structure involving an infinite tape on which symbols can be printed and removed. Turing was able to show that what can be formally computed can be proven to be computable on this machine. However, to succeed in the imitation game, a classical machine would have … WebJul 6, 2024 · In each step of its computation, a two- tape Turing machine reads the symbols under its read/write heads on both tapes. Based on these symbols and on its current state, it can write a new symbol onto each tape, independently move the read/write head on each tape one cell to the left or right, and change state.
