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
The Set Covering problem (SCP) is a well known combinatorial optimization problem, which is NP-hard. We conducted a comparative study of nine different approximation algorithms for the SCP, including several greedy variants, fractional relaxations, randomized algorithms and a neural network algorith
