Reoptimization of maximum weight induced hereditary subgraph problems
The reoptimization issue studied in this paper can be described as follows: given an instance I of some problem Π, an optimal solution OPT for Π in I and an instance I ′ resulting from a local perturbation of I that consists of insertions or removals of a small number of data, we wish to use OPT in order to solve Π in I , either optimally or by guaranteeing an approximation ratio better than th...

متن کاملOn-line maximum-order induced hereditary subgraph problems (Preliminary version)
We first study the competitivity ratio for the on-line version of the problem of finding a maximum-order induced subgraph satisfying some hereditary property, under the hypothesis that the input graph is revealed by clusters. Then, we focus ourselves on two of the most known instantiations of this problem, the maximum independent set and the maximum clique.
متن کاملOn-Line Computation and Maximum-Weighted Hereditary Subgraph Problems
In this paper1 we study the on-line version of maximum-weighted hereditary subgraph problems. In our on-line model, the final instance (a graph with n vertices) is revealed in t clusters, n t ≤ ≤ 2 . We first focus on an on-line version of the maximumweighted hereditary subgraph problem. Then, we deal with the particular case of the independent set problem. We are interested in two types of res...
