Karp reduction
WebbFig. 1: Reducing H to U. It is easy to see that if U is solvable in polynomial time, then so is H. We assume that the translation module runs in polynomial time. If so, we say we have a polynomial reduction of problem H to problem U, which is denoted H P U. This is called a Karp reduction.

WebbKarp reductions are also more restrictive than Cook reductions (i.e. Cook reductions relate more decision problems; equivalently a Karp reduction is also a Cook reduction), so … WebbWe have had several questions about the relation of Cook and Karp reductions.It's clear that Cook reductions (polynomial-time Turing reductions) do not define the same notion of NP-completeness as Karp reductions (polynomial-time …
Webb10 feb. 2024 · A Karp reduction provides a Cook reduction, since a Turing machine could decide L1 L 1 by calculating g(x) g ( x) on any input and determining whether g(x) ∈L2 g ( x) ∈ L 2. Note that it is a stronger condition than a Cook reduction. For instance, this machine requires only one use of the oracle.
