Connected (Dense) Partition for Tree-Like Graphs

Katrin Casel, Archontia C. Giannopoulou, Aikaterini Niklanovits

We focus on two variants of graph partitioning problems, connected partition and dense partition. Formally, given a graph and a partition of its vertices $\mathcal P=\{P_…

Combining Crown Structures for Vulnerability Measures

Katrin Casel, Tobias Friedrich, Aikaterini Niklanovits +2

Over the past decades, various metrics have emerged in graph theory to grasp the complex nature of network vulnerability. In this paper, we study two specific measures: (weighted)…

Fair Correlation Clustering in Forests

Katrin Casel, Tobias Friedrich, Martin Schirneck +1

The study of algorithmic fairness received growing attention recently. This stems from the awareness that bias in the input data for machine learning systems may result in discrimi…

Efficient Constructions for the Győri-Lovász Theorem on Almost Chordal Graphs

Katrin Casel, Tobias Friedrich, Davis Issac +2

In the 1970s, Győri and Lovász showed that for a -connected -vertex graph, a given set of terminal vertices and natural numbers satisfying…

Fixed-Parameter Sensitivity Oracles

Davide Bilò, Katrin Casel, Keerti Choudhary +5

We combine ideas from distance sensitivity oracles (DSOs) and fixed-parameter tractability (FPT) to design sensitivity oracles for FPT graph problems. An oracle with sensitivity $f…

Connected -partition of -connected graphs and -claw-free graphs

Ralf Borndörfer, Katrin Casel, Davis Issac +3

A connected partition is a partition of the vertices of a graph into sets that induce connected subgraphs. Such partitions naturally occur in many application areas such as road ne…
