这个问题有一个npo(np optimization problem)的变种,即:找到满足条件的最小顶点集,也就是使得满足条件下最小|V'|值。 首先可以看出,这是两类完全不同的问题,set cover属于集合一类问题,应用于计算机科学以及计算理论方面。vertex cover,属于图论一类问题,应用于计算机科学、计算理论、图论、数学等等方面。 如果这篇...
Set Cover问题的贪心近似算法分析 问题描述 全集U={e1,e2,...,en}U={e1,e2,...,en}被划分为一系列的子集S={S1,S2,...,Sk}S={S1,S2,...,Sk}。且存在一个cost函数c:S→R+c:S→R+。 目标是挑选子集使其覆盖所有全集UU的元素同时cost最小...
Here we consider using quantum annealing to solve Set Cover with Pairs (SCP), an NP-hard combinatorial optimization problem that plays an important role in networking, computational biology and biochemistry. We show an explicit construction of Ising Hamiltonians whose ground states encode the solution...

1.1.1 VERTEX-COVER ≤ P SET-COVER Pf. Given a VERTEX-COVER instance G = (V, E) and k, we construct a SET-COVER instance (U, S, k) that has a set cover of size k iff G has a vertex cover of size k. 给你一个顶点覆盖我们一定可以构造出一个集合覆盖实列,集合覆盖的解K就是顶...
In this paper, we give new results for the set cover problem in the fully dynamic model. In this model, the set of active elements to be covered changes over time. The goal is to maintain a near-optimal solution for the currently active elements, while making few changes in each...
