WebWhen it fails, the problem is NP-hard and, in fact, APX-complete (hence, cannot be approximated better than some constant). Thus, we establish a dichotomy in the complexity of computing an optimal S-repair. We present general analysis techniques for the complexity of computing an optimal U-repair, some based on the dichotomy for S-repairs.

WebMay 21, 2012 · A dichotomy in the complexity of deletion propagation with functional dependencies. Pages 191–202. ... and it is even hard to realize an approximation ratio … It is a very simple and robust method, but it is also relatively slow. Because of this, it is often used to obtain a rough approximation to a solution which is then used as a starting point for more rapidly converging methods. The method is also called the interval halving method, the binary search method, or the … See more In mathematics, the bisection method is a root-finding method that applies to any continuous function for which one knows two values with opposite signs. The method consists of repeatedly bisecting the interval defined … See more The method is applicable for numerically solving the equation f(x) = 0 for the real variable x, where f is a continuous function defined on an interval [a, b] and where f(a) and f(b) have … See more • Binary search algorithm • Lehmer–Schur algorithm, generalization of the bisection method in the complex plane • Nested intervals See more • Weisstein, Eric W.
