Complexity theory oracle

  • Can an Oracle solve the halting problem?

    Oracles and halting problems
    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..

  • What is an Oracle Computing?

    Oracle Cloud is a cloud based computing service offered by Oracle Corporation.
    It provides storage, servers, network, applications and services through a global network of Oracle Corporation managed data centers.
    The company allows these services to be provisioned on demand over the Internet..

  • What is an Oracle in algorithms?

    An oracle, , is an unexposed operation that is used as input to another algorithm.
    Often, such operations are defined using a classical function f : { 0 , 1 } n → { 0 , 1 } m , which takes an -bit binary input and produces an -bit binary output..

  • 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.
In complexity theory and computability theory, an oracle machine is an abstract machine used to study decision problems. It can be visualized as a Turing machine with a black box, called an oracle, which is able to solve certain problems in a single operation. The problem can be of any complexity class.

Topics referred to by the same term

An oracle a person or thing considered to provide wise and insightful counsel or prophetic predictions.
In mathematical optimization, oracle complexity is a standard theoretical framework to study the computational requirements for solving classes of optimization problems.
It is suitable for analyzing iterative algorithms which proceed by computing local information about the objective function at various points.
The framework has been used to provide tight worst-case guarantees on the number of required iterations, for several important classes of optimization problems.
In cryptography, a random oracle is an oracle that responds to every unique query with a (truly) random response chosen uniformly from its output domain.
If a query is repeated, it responds the same way every time that query is submitted.
