Chatin's constant gives a sort-of probabilistic answer to the question that these were designed to solve.
Chatin's constant gives a sort-of probabilistic answer to the question that these were designed to solve. Two dimensional ones on rectangular grids are sometimes called Turmites. The thesis of their namesake and Church states that every computable algorithm corresponds to one. The so-called formalism of these is equivalent to the lambda calculus and both can show that the halting problem is un-decidable. Consisting of a read/write head, instruction set, and tape, for ten points, identify this hypothetical device named for a pioneering British computer scientist.
