[HTML][HTML] Algorithmic aspects of clique-transversal and clique-independent sets

V Guruswami, CP Rangan - Discrete Applied Mathematics, 2000 - Elsevier
A minimum clique-transversal set MCT (G) of a graph G=(V, E) is a set S⊆ V of minimum
cardinality that meets all maximal cliques in G. A maximum clique-independent set MCI (G) …

Upper clique transversals in graphs

M Milanič, Y Uno - International Workshop on Graph-Theoretic Concepts …, 2023 - Springer
A clique transversal in a graph is a set of vertices intersecting all maximal cliques. The
problem of determining the minimum size of a clique transversal has received considerable …

The geodesic-transversal problem

P Manuel, B Brešar, S Klavžar - Applied Mathematics and Computation, 2022 - Elsevier
A maximal geodesic in a graph is a geodesic (alias shortest path) which is not a subpath of a
longer geodesic. The geodesic-transversal problem in a graph G is introduced as the task to …

[HTML][HTML] Distance-hereditary graphs are clique-perfect

CM Lee, MS Chang - Discrete Applied Mathematics, 2006 - Elsevier
In this paper, we show that the clique-transversal number τC (G) and the clique-
independence number αC (G) are equal for any distance-hereditary graph G. As a byproduct …

Exponential speedup of fixed-parameter algorithms for classes of graphs excluding single-crossing graphs as minors

ED Demaine, MT Hajiaghayi, DM Thilikos - Algorithmica, 2005 - Springer
We present a fixed-parameter algorithm that constructively solves the k-dominating set
problem on any class of graphs excluding a single-crossing graph (a graph that can be …

[HTML][HTML] On some graph classes related to perfect graphs: A survey

F Bonomo-Braberman, G Durán, MD Safe… - Discrete Applied …, 2020 - Elsevier
Perfect graphs form a well-known class of graphs introduced by Berge in the 1960s in terms
of a min–max type equality involving two famous graph parameters. In this work, we survey …

[HTML][HTML] Algorithmic aspects of some variations of clique transversal and clique independent sets on graphs

CM Lee - Algorithms, 2021 - mdpi.com
This paper studies the maximum-clique independence problem and some variations of the
clique transversal problem such as the {k}-clique, maximum-clique, minus clique, signed …

Connected Vertex Cover for -Free Graphs

M Johnson, G Paesani, D Paulusma - Algorithmica, 2020 - Springer
Abstract The Connected Vertex Cover problem is to decide if a graph G has a vertex cover of
size at most k that induces a connected subgraph of G. This is a well-studied problem …

On clique-transversals and clique-independent sets

G Durán, MC Lin, JL Szwarcfiter - Annals of Operations Research, 2002 - Springer
A clique-transversal of a graph G is a subset of vertices intersecting all the cliques of G. A
clique-independent set is a subset of pairwise disjoint cliques of G. Denote by τ C (G) and α …

Maximum clique transversals

MS Chang, T Kloks, CM Lee - … Workshop on Graph-Theoretic Concepts in …, 2001 - Springer
A maximum clique transversal set in a graph G is a set S of vertices such that every
maximum clique of G contains at least a vertex in S. Clearly, removing a maximum clique …
