What Is Computability Theory ?Weber, RebeccaCollege, Dartmouth
In computability theory, an undecidable problem isa type of computational problem that requires a yes/no answer, but where there cannot possibly be any computer program that always gives the correct answer; that is, any possible program would sometimes give the wrong answer or run forever without ...
It has long been assumed that the Turing machine computes all the functions that are computable in any reasonable sense. It is therefore assumed to be a sufficient model for computability. What then, is one to make of the slow trickle of papers that discuss models which can compute more than...
In virtue of what is something a computer? Why do we say a slide rule is a computer but an egg beater is not? —Churchland and Sejnowski (1992, p. 61) … everyone who taps at a keyboard, opening a spreadsheet or a word-processing program, is working on an incarnation of a Turing ...
What is Queue Automata - Discover the concept of Queue Automata, its structure, functioning, and applications in automata theory.
Spatial complexity is defined here as the difficulty to simplify the structure or form of a 2-and-higher-dimensional surface or object. The study of spatial complexity refers to the geographical space, to mathematically abstract spaces, to physical objects, or to any surface or object, in an-...

Note that the existence of this language is not straightforward as it must involve Turing-computability issues. Indeed, if one does not insist on the fact that the local algorithm must be a Turing-computable function, then the two classes LD and Π1local would be identical. For instance, ...
2) Issues relating to computability, and the need to incorporate more and more complexity while handling the trade-off with usability: “Computability: To integrate inter-dependent: sectors, scales (spatial) ecosystem services, scales (temporal) adaptations, future scenario space, uncertainty etc.”....
Now give it something where play units are randomly drawn, say like mahjong, then see what it gets up to, as the cominations etc then possibly become factorial, and Turing and Church had things to say about computability (which comes in two forms I believe, one it likely can't be done...
