Reoptimization of set covering problems

  • Published:
Cybernetics and Systems Analysis Aims and scope

Abstract

If an element is inserted into or removed from a set, then the set covering problem can be reoptimized with some ratio \( \left( {2 - \frac{1}{{\ln m + 1}}} \right) \), where m is the number of elements of the set. A similar result holds if an arbitrary number 1 < p < m of elements of the set is inserted or removed.
