If B ∈ P, then A ∈ P (You can just reduce from A to B in polynomial time and solve B in polynomial time. Combining this gives polynomial time algorithm for A) 2. If B ∈ NP, then A ∈ NP. 3. If A is NP-hard, then B is NP-hard. chinn feed millWebAbstract. Dealing with NP-hard problems, kernelization is a fundamental notion for polynomial-time data reduction with performance guarantees: in polynomial time, a problem instance is reduced to an equivalent instance with size upper-bounded by a function of a parameter chosen in advance. granite island music festivalIn computational complexity theory, a polynomial-time reduction is a method for solving one problem using another. One shows that if a hypothetical subroutine solving the second problem exists, then the first problem can be solved by transforming or reducing it to inputs for the second problem and … See more The three most common types of polynomial-time reduction, from the most to the least restrictive, are polynomial-time many-one reductions, truth-table reductions, and Turing reductions.
