ORACLE (computer) ORACLE (computer) The ORACLE or "Oak Ridge Automatic Computer and Logical Engine", an early computer built by Oak Ridge National Laboratory, was based on the IAS architecture developed by John von Neumann. The "Oak Ridge National Laboratory Review" states: [Oak Ridge National] Laboratory engineers assisted Argonne [National Laboratory] during the early 1950s in design and fabrication of the Oak Ridge Automatic Computer and Logical Engine. Its name was selected with reference to a lyrical acronym from Greek mythology—ORACLE, defined as 'a shrine in which a deity reveals hidden knowledge.' Assembled before the development of transistors and microchips, the ORACLE was
Computer-assisted proof the runtime environment and hardware. Other mathematicians believe that lengthy computer-assisted proofs should be regarded as "calculations", rather than "proofs": the proof algorithm itself should be proved valid, so that its use can then be regarded as a mere "verification". Arguments that computer-assisted proofs are subject to errors in their source programs, compilers, and hardware can be resolved by providing a formal proof of correctness for the computer program (an approach which was successfully applied to the four-color theorem in 2005) as well as replicating the result using different programming languages, different compilers, and different computer hardware. Another possible way
