A set is Turing-reducible to when an oracle machine with membership oracle computes the characteristic function of . Unlike a many-one reduction, it may make adaptive queries and reverse or combine oracle answers.
In computational theory, a Turing reduction is a method used to compare the relative difficulty of computational problems. Specifically, a problem \( A \) is Turing reducible to a problem \( B \) if there exists a Turing machine that can solve \( A \) using an oracle that solves \( B \). This means that the Turing machine can ask the oracle questions about problem \( B \) and use the answers to help solve problem \( A \).
