In computational complexity theory and computability theory, a search problem is a type of computational problem represented by a binary relation. If R is a binary relation such that field(R) ⊆ Γ⁺ and T is a Turing machine, then T calculates R if: If x is such that there is some y such that R(x, y) then T accepts x with output z such that R(x, z) (there may be multiple y, and T need only find one of them) If x is such that there is no y such that R(x, y) then T rejects x Intuitively, the problem consists in finding structure "y" in object "x".
