A set A is polynomial-time reducible to a set if there is a Turing reduction of to that runs in polynomial time. The concept of log-space reduction is similar. These reductions are stronger in the sense that they provide a finer distinction into equivalence classes, and satisfy more restrictive requirements than Turing reductions.
On set Eileen Hughes asked Eugene Walter (the American dialogue coach) why Fellini wanted a "hermaphrodite" in the film: "Nowadays, if a family had a hermaphrodite, they would keep it a deep dark secret or have an operation, but in these times, it is a magical thing, a gift of the gods, and the child becomes an oracle." Italy [8] [9] 1969
Simon's problem considers access to a function : {,} {,}, as implemented by a black box or an oracle. This function is promised to be either a one-to-one function, or a two-to-one function; if is two-to-one, it is furthermore promised that two inputs and ′ evaluate to the same value if and only if and ′ differ in a fixed set of bits. I.e.,
A consistency oracle compares the results of one test execution to another for similarity. [16] This is another example of a derived test oracle. An oracle for a software program might be a second program that uses a different algorithm to evaluate the same mathematical expression as the product under test. This is an example of a pseudo-oracle ...
Lycurgus Consulting the Pythia (1835/1845), as imagined by Eugène Delacroix.. Pythia was the priestess presiding over the Oracle of Apollo at Delphi.There are more than 500 supposed oracular statements which have survived from various sources referring to the oracle at Delphi.
The Oracle unified method (OUM), first released by Oracle Corporation in 2006, is a standards-based method with roots in the unified process (UP). OUM is business-process and use-case driven and includes support for the Unified Modeling Language (UML), though the use of UML is not required. OUM combines these standards with aspects of Oracle's ...
The DUAL table is a special one-row, one-column table present by default in Oracle and other database installations. In Oracle, the table has a single VARCHAR2(1) column called DUMMY that has a value of 'X'. It is suitable for use in selecting a pseudo column such as SYSDATE or USER.
In comparing Oracle Internet Directory with its competitors, Oracle Corporation stresses that it uses as its foundation an Oracle database; whereas many competing products (such as Oracle Directory Server Enterprise Edition and Novell eDirectory) do not rely on an enterprise-strength relational database, but instead on embedded database engines similar to Berkeley DB.
