Subexponential Parameterized Directed Steiner Network Problems on Planar Graphs: a Complete Classification
Esther Galby, Sandor Kisfaludi-Bak, Daniel Marx +1
In the Directed Steiner Network problem, the input is a directed graph G, a subset T of k vertices of G called the terminals, and a demand graph D on T. The task is to find a subgr…
Domination and Cut Problems on Chordal Graphs with Bounded Leafage
Esther Galby, Daniel Marx, Philipp Schepper +2
The leafage of a chordal graph G is the minimum integer l such that G can be realized as an intersection graph of subtrees of a tree with l leaves. We consider structural parameter…
Metric Dimension Parameterized by Feedback Vertex Set and Other Structural Parameters
Esther Galby, Liana Khazaliya, Fionn Mc Inerney +2
For a graph , a subset is called a \emph{resolving set} if for any two vertices , there exists a vertex such that …
Parameterized Complexity of Weighted Multicut in Trees
Esther Galby, Dániel Marx, Philipp Schepper +2
The Edge Multicut problem is a classical cut problem where given an undirected graph , a set of pairs of vertices , and a budget , the goal is to determine if th…
