Oracle machine - Wikipedia

A machine with an oracle for the halting problem can determine whether particular Turing machines will halt on particular inputs, but it cannot determine, in general, whether machines equivalent to itself will halt. This creates a hierarchy of machines, each with a more powerful halting oracle and an even harder halting problem. This hierarchy of machines can be used to define the arithmetical hierarchy (Börger 1989). WebJun 30, 2016 · While a halting oracle can predict the behavior of any isolated Turing machine, it cannot predict the behavior of another Turing machine that has access to a halting oracle.

WebRAC can cram an infinite number of computations into a single second.It is indifferent to the algorithmic complexity of the task set to it: everything runs, not in exponential or polynomial time, but in bounded time.It can therefore solve the halting problem for Turing machines (which Turing proved algorithmically undecidable) by running a ... WebOne of the possible interpretation: having an oracle that tells the exact values of Kolmogorov complexity of any given string, one can use it to solve halting problem (computably, with oracle calls).

"WebFor example, a halting oracle decides whether any program halts, in one time-step. No one could build or even specify such an oracle, but mathematicians do not have to bother with such trivial details. "Let there be a D(A) such that, for any A, D(A) decides whether A halts (in one time-step)." See, the halting problem is easy to solve! " - Halting oracle

An oracle for level $\exists$ would take care of a number of the classical open problems, a (strictly stronger) oracle for the $\forall\exists$ would take care of probably the rest.
