[HTML][HTML] The most vital nodes with respect to independent set and vertex cover

C Bazgan, S Toubaline, Z Tuza - Discrete Applied Mathematics, 2011 - Elsevier
Given an undirected graph with weights on its vertices, the k most vital nodes independent
set (k most vital nodes vertex cover) problem consists of determining a set of k vertices …

Reducing the clique and chromatic number via edge contractions and vertex deletions

D Paulusma, C Picouleau, B Ries - … , ISCO 2016, Vietri sul Mare, Italy, May …, 2016 - Springer
We consider the following problem: can a certain graph parameter of some given graph G
be reduced by at least d, for some integer d, via at most k graph operations from some …

Blockers for the stability number and the chromatic number

C Bazgan, C Bentz, C Picouleau, B Ries - Graphs and Combinatorics, 2015 - Springer
Given an undirected graph G=(V, E) and two positive integers k and d, we are interested in
finding a set of edges (resp. non-edges) of size at most k to delete (resp. to add) in such a …

Complexity of determining the most vital elements for the 1-median and 1-center location problems

C Bazgan, S Toubaline, D Vanderpooten - International Conference on …, 2010 - Springer
We consider the k most vital edges (nodes) and min edge (node) blocker versions of the 1-
median and 1-center location problems. Given a weighted connected graph with distances …

A large and natural Class of - and -complete Problems in Bilevel and Robust Optimization

C Grüne, L Wulf - arxiv preprint arxiv:2311.10540, 2023 - arxiv.org
Because $\Sigma^ p_2 $-and $\Sigma^ p_3 $-hardness proofs are usually tedious and
difficult, not so many complete problems for these classes are known. This is especially true …
