The reoptimization issue studied in this paper can be described as follows: given an instance I of some problem @P, an optimal solution OPT for @P in I and an instance I^' resulting from a local modification of I that consists of insertions or removals of a small number of data, we wish to use OPT in order to solve @P in I^'. The aim is to achieve either a better approximation ratio or a better running time (or both) than guaranteed by ex nihilo computation. We use this setting in order to study weighted versions of several representatives of a broad class of problems known in the literature as maximum induced hereditary subgraph problems. The main problems studied are max independent set, maxk-colorable subgraph and max split subgraph under vertex insertions and deletions.
