In 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 calling the subroutine one or more times. If both the time required to transform the first problem to the second, and the number of times the subroutine is called is polynomial, then … Webcomputing a local minimizer of the problem is polynomial-time doable. 2 The Hardness Theorem 1. For a given real number v, it is NP-hard to decide if the minimal objective value of problem (1) is less than or equal to v. Proof. We present a poly-time reduction from the well known NP-complete partition problem.
