Released packing functions in graphs

Pablo Fekete, Erica Hinrichsen, Valeria Leoni +1

We introduce and start the study of a variant of packing functions in graphs. Given a graph with vertex set and nonnegative integer vectors , $\b…

On the proper interval completion problem within some chordal subclasses

François Dross, Claire Hilaire, Ivo Koch +4

Given a property (graph class) , a graph , and an integer , the \emph{-completion} problem consists in deciding whether we can turn into a graph with the property $…

Efficient algorithms for tuple domination on co-biconvex graphs and web graphs

María Patricia Dobson, Valeria Leoni, María Inés Lopez Pujato

A vertex in a graph dominates itself and each of its adjacent vertices. The \emph{-tuple domination problem}, for a fixed positive integer , is to find a minimum sized vertex…

Tuple domination on graphs with the consecutive-zeros property

María Patricia Dobson, Valeria Leoni, María Inés Lopez Pujato

The -tuple domination problem, for a fixed positive integer , is to find a minimum sized vertex subset such that every vertex in the graph is dominated by at least vertic…

New Algorithms for Weighted -Domination and Total -Domination Problems in Proper Interval Graphs

Nina Chiarelli, Tatiana Romina Hartinger, Valeria Alejandra Leoni +2

Given a positive integer , a -dominating set in a graph is a set of vertices such that every vertex not in the set has at least neighbors in the set. A total -domi…
