集合覆盖问题(Set Covering Problem,简称SCP)是运筹学研究中典型的组合优化问题之一,工业领域里的许多实际问题都可建模为集合覆盖问题,如资源选择问题、设施选址问题(移动基站的选址、物流中心的选址)等。-m种软件 -我们希望我们的系统能有n个软件,集合为U(比如手机里面有视频软件,学习软件等等)-第...

In the weighted set-cover problem, we are given a finite set S and a collection of its subsets. A non-negative weight wj is associated with each . The problem is to find a subcollection of with minimum weight so that the union of its sets is equal to . This problem is a classic ...

We address a version of the set-cover problem where we do not know the sets initially (and hence referred to as covert) but we can query an element to find out which sets contain this element as well as query a set to know the elements. We want to find a small set-cover using a...
closest vector problem (CVP)shortest vector problem (SVP)The restricted parameter range set cover problem is a weak form of the NP-hard set cover problem with the restricted range of parameters. We give a polynomial time algorithm for this problem by lattices.doi:10.1007/s11464-014-0429-8Hao...
In this paper, we study the computational complexity and approximation complexity of the connected set-cover problem. We derive necessary and sufficient conditions for the connected set-cover problem to have a polynomial-time algorithm. We also present a sufficient condition for the existence of a ...
0. Raz and Safra [18] proved that if P = N P then for some constant c, the unweighted set cover problem cannot be approximated within a factor c log n. This result shows that the greedy algorithm is an asymptotically best possible approximation algorithm for the weighted and unweighted ...
内容提示: Semi-Streaming Set Cover(Full Version)Yuval Emek ∗ Adi Ros´ en †AbstractThis paper studies the set cover problem under the semi-streaming model. The underlyingset system is formalized in terms of a hypergraph G = (V,E) whose edges arrive one-by-one andthe goal is to ...
