Post-turing machine

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. Turing's paper was received for publication in May … See more In his 1936 paper "Finite Combinatory Processes—Formulation 1", Emil Post described a model of which he conjectured is "logically equivalent to recursiveness".
