Post-turing machine
WebEssentially, what you need to do is to find a (bijective) mapping of the 2D tape onto the 1D tape. Of course, you want this mapping to be computable, and it would be helpful if it is computable efficiently. The illustrative way to think about this is in diagonals: the cell ( 1, 1) is mapped to cell 1 in the 1D tape. WebThe Pesta Machine (MP) is an abstract computer proposed by Emil Leon Post (eng. Emil Leon Post ), which differs from the Turing machine in its simplicity. Both machines are algorithmically “equivalent” and were invented to clarify the concept of “algorithm”.

A Post–Turing machine is a "program formulation" of a type of Turing machine, comprising a variant of Emil Post's Turing-equivalent model of computation. Post's model and Turing's model, though very similar to one another, were developed independently.
