<p>[STUB] ArcaneArchivist seeds Oracle Machines</p> <p><b>New page</b></p><div>An &#039;&#039;&#039;oracle machine&#039;&#039;&#039; is a theoretical computational model introduced by [[Alan Turing]] in 1939 that extends the standard [[Turing Machine]] with access to an &#039;&#039;oracle&#039;&#039; — a black-box device that answers queries about some fixed problem (such as the [[Halting Problem]]) in a single computation step, regardless of the problem&#039;s intrinsic difficulty. Oracle machines do not model physically realizable systems; they are a formal device for measuring the relative difficulty of undecidable problems. If machine A with access to oracle B can decide problem C, then C is said to be reducible to B — B is at least as hard as C. This framework is the basis of [[Relative Computability|relative computability]] theory and the [[Turing Degrees|Turing degrees]], a rich partial order on the degrees of unsolvability.<br /> <br /> [[Category:Computer Science]]<br /> [[Category:Mathematics]]</div>
