集合覆盖问题 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。 简单的应用 软件用数字代替.png -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...
1) set-cover problem 最小集合覆盖问题1. Through the problem of lossy links inference is mapped to minimal set-cover problem,the algorithm based on heuristic strategy is proposed. 通过将失效链路推断问题映射为最小集合覆盖问题,提出了一种基于启发策略的失效链路推断算法。

Set Cover Problem (集合覆盖问题) 假设我们有个全集U (Universal Set), 以及m个⼦子集合 𝑆1 ,𝑆2 …,𝑆m, 目标是要寻找最少的集合,使得集合的union等于U 例子: U = {1,2,3,4,5}, S: {𝑆 W ={1,2,3}, 𝑆 X ={2,4}, 𝑆 Y ={1,3}, ...
4.1.1 Set covering/set partitioning problem Historically and still today, the SCP/SPP model formulation can be characterized as the “standard model formulation” in RCSP literature (see Fig. 4). In general, the railway crew scheduling problem is to cover each trip at least once with a feasib...
What is the set cover problemStern, Tamara I
The SET COVER problem is tantalizingly simple to de- scribe: given a collection F of sets, each containing a subset of a universe U of objects, find a smallest sub- collection A of F such that every object in U is included in at least one of the sets in A. However, like many ...

We introduce the batched set cover problem, which is a gen- eralization of the online set cover problem. In this problem, the elements of the ground set that need to be covered arrive in batches. Our main technical contribution is a tight (Hm-2z+1) lower bound on the com- petitive ...
