Complexity and Algorithms for Semipaired Domination in Graphs [article]

Michael A. Henning, Arti Pandey, Vikash Tripathi
2019 arXiv   pre-print
We also propose a 1+(2Δ+2)-approximation algorithm for the Minimum Semipaired Domination problem, where Δ denote the maximum degree of the graph and show that the Minimum Semipaired Domination problem  ...  We show that the decision version of the Minimum Semipaired Domination problem is NP-complete for bipartite graphs and split graphs.  ...  Complexity difference between paired domination and semipaired domination In this section, we make an observation on complexity difference between paired domination and semipaired domination.  ...

Semipaired Domination in Some Subclasses of Chordal Graphs [article]

Michael A. Henning, Arti Pandey, Vikash Tripathi
2021 arXiv   pre-print
In addition, we prove that the Minimum Semipaired Domination problem is APX-complete for graphs with maximum degree 3.  ...  In this paper, we show that the decision version of the Minimum Semipaired Domination problem remains NP-complete for split graphs, a subclass of chordal graphs.  ...  Complexity difference between paired domination and semipaired domination In this subsection, we discuss the complexity difference between paired domination and semipaired domination.  ...
