Algorithmic Aspects of Upper Domination
In this paper we study combinatorial and algorithmic resp. complexity questions of upper domination, i.e., the maximum cardinality of a minimal dominating set in a graph. We give a full classification of the related maximisation and minimisation problems, as well as the related parameterised problems, on general graphs and on graphs of bounded degree, and we also study planar graphs.
متن کاملAlgorithmic Aspects of Semitotal Domination in Graphs
For a graph G = (V,E), a set D ⊆ V is called a semitotal dominating set of G if D is a dominating set of G, and every vertex in D is within distance 2 of another vertex of D. The Minimum Semitotal Domination problem is to find a semitotal dominating set of minimum cardinality. Given a graph G and a positive integer k, the Semitotal Domination Decision problem is to decide whether G has a semito...
متن کاملAlgorithmic Aspects of Domination in Graphs
Graph theory was founded by Euler [78] in 1736 as a generalization to the solution of the famous problem of the Könisberg bridges. From 1736 to 1936, the same concept as graph, but under different names, was used in various scientific fields as models of real world problems, see the historic book by Biggs, Lloyd andWilson [19]. This chapter intents to survey the domination problem in graph theo...
متن کاملAlgorithmic Aspects of Disjunctive Domination in Graphs
For a graph G = (V,E), a set D ⊆ V is called a disjunctive dominating set of G if for every vertex v ∈ V \D, v is either adjacent to a vertex of D or has at least two vertices in D at distance 2 from it. The cardinality of a minimum disjunctive dominating set of G is called the disjunctive domination number of graph G, and is denoted by γ 2 (G). The MINIMUM DISJUNCTIVE DOMINATION PROBLEM (MDDP)...
متن کاملAlgorithmic Aspects of Upper Domination: A Parameterised Perspective
This paper studies Upper Domination, i.e., the problem of computing the maximum cardinality of a minimal dominating set in a graph, with a focus on parameterised complexity. Our main results include W[1]-hardness for Upper Domination, contrasting FPT membership for the parameterised dual Co-Upper Domination. The study of structural properties also yields some insight into Upper Total Domination...
