Structural Parameterizations for Eternal Vertex Cover

Neeldhara Misra, Sebastian Ordyniak, Giacomo Paesani +1

Eternal Vertex Cover (EVC) is a turn-based attacker-defender game on an undirected graph . To begin with, the defender places guards on vertices of . The attacker, on the…

Explaining Decisions in ML Models: a Parameterized Complexity Analysis (Part I)

Sebastian Ordyniak, Giacomo Paesani, Mateusz Rychlicki +1

This paper presents a comprehensive theoretical investigation into the parameterized complexity of explanation problems in various machine learning (ML) models. Contrary to the pre…

Finding -Cuts in Probe -Free Graphs

Konrad K. Dabrowski, Tala Eagling-Vose, Matthew Johnson +2

For an integer , the -Cut problem is that of deciding whether a graph has an edge cut in which each vertex is adjacent to at most vertices on the opposite side of t…

A Tight Subexponential-time Algorithm for Two-Page Book Embedding

Robert Ganian, Haiko Mueller, Sebastian Ordyniak +2

A book embedding of a graph is a drawing that maps vertices onto a line and edges to simple pairwise non-crossing curves drawn into pages, which are half-planes bounded by that lin…

Steiner Trees for Hereditary Graph Classes: a Treewidth Perspective

Hans Bodlaender, Nick Brettell, Matthew Johnson +3

We consider the classical problems (Edge) Steiner Tree and Vertex Steiner Tree after restricting the input to some class of graphs characterized by a small set of forbidden induced…
