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_…
A New Approach for Approximating Directed Rooted Networks
Sarel Cohen, Lior Kamma, Aikaterini Niklanovits
We consider the k-outconnected directed Steiner tree problem (k-DST). Given a directed edge-weighted graph , where , and an integer , the goal i…
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)…
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…
Balanced Crown Decomposition for Connectivity Constraints
Katrin Casel, Tobias Friedrich, Davis Issac +2
We introduce the balanced crown decomposition that captures the structure imposed on graphs by their connected induced subgraphs of a given size. Such subgraphs are a popular model…
