A reoptimization problem describes the following scenario: Given an instance of an optimization problem together with an optimal solution for it, we want to find a good solution for a locally modified instance. In this paper, we deal with reoptimization variants of the shortest common superstring problem where the local modifications consist of adding or removing a single string. We show NP-hardness of these reoptimization problems and design several approximation algorithms for them.
