In computability theory, many reducibility relations (also called reductions, reducibilities, and notions of reducibility) are studied. They are motivated by the question: given sets $${\displaystyle A}$$ and $${\displaystyle B}$$ of natural numbers, is it possible to effectively convert a method for deciding … Visa mer A reducibility relation is a binary relation on sets of natural numbers that is • Reflexive: Every set is reducible to itself. • Transitive: If a set $${\displaystyle A}$$ is reducible to a set $${\displaystyle B}$$ and $${\displaystyle B}$$ is … Visa mer • Stanford Encyclopedia of Philosophy: Recursive Functions Visa mer The strong reducibilities include • One-one reducibility: $${\displaystyle A}$$ is one-one reducible to $${\displaystyle B}$$ if there is a computable one-to-one function Visa mer Although Turing reducibility is the most general reducibility that is effective, weaker reducibility relations are commonly studied.
