In computability theory, a Turing reduction from a decision problem A {\displaystyle A} to a decision problem B {\displaystyle B} is an oracle machine...

polynomial-time reduction, from the most to the least restrictive, are polynomial-time many-one reductions, truth-table reductions, and Turing reductions. The most...

computational complexity theory, a log-space reduction is a reduction computable by a deterministic Turing machine using logarithmic space. Conceptually...

{\displaystyle L_{1}} . Many-one reductions are a special case and stronger form of Turing reductions. With many-one reductions, the oracle (that is, our solution...

two main types of reductions used in computational complexity, the many-one reduction and the Turing reduction. Many-one reductions map instances of one...

The Turing pattern is a concept introduced by English mathematician Alan Turing in a 1952 paper titled "The Chemical Basis of Morphogenesis" which describes...

for an example. The definition of NP-easy uses a Turing reduction rather than a many-one reduction because the answers to problem Y are only TRUE or...

term reduction was used in the technical meaning of a polynomial-time many-one reduction. Another type of reduction is polynomial-time Turing reduction. A...

what is now known as the Turing test to the general public. Turing's paper considers the question "Can machines think?" Turing says that since the words...

patterns have come to be known as Turing patterns. For example, it has been postulated that the protein VEGFC can form Turing patterns to govern the formation...
