Penrose's The Emperor's New Mind discusses the language-accepting capabilities of this model, which is often specified using a 7-tuple.
One construct that has an equivalent function to this mathematical model, but is governed by the Cohen-Kung theorem and makes uses of a two dimensional grid is called Langton's Ant. Penrose's The Emperor's New Mind discusses the language-accepting capabilities of this model, which is often specified using a 7-tuple. This model is equivalent to an unrestricted grammar, a pushdown automaton with two stacks or one queue. It is also specified in the same way as a linear bounded automaton, but there is no space constriction requirement. This model consists of a state control, a read and writing head and a sequence of blank infinite cells used for writing. For 10 points, name this hypothetical device that is believed to be able to simulate all modern computers, named for an English mathematician.
