## Abstract We study a generalization of the weighted set covering problem where every element needs to be covered multiple times. When no set contains more than two elements, we can solve the problem in polynomial time by solving a corresponding weighted perfect __b__βmatching problem. In general,
In this paper we prove that the approximate solutions to the Min-Weighted Set Cover Problem provided by Chvatal's algorithm are combinatorially k-stable with respect to element insertions. Intuitively speaking, we define an approximate solution as combinatorially k-stable with respect to an update
