Changing a given configuration in a graph into another one is known as a re-configuration problem. Such problems have recently received much interest in the context of algorithmic …
The tangle tree-decomposition theorem, proved by Robertson and Seymour in their seminal graph minors series, turns out to be an extremely valuable tool in structural and algorithmic …
This paper revisits the classical edge-disjoint paths (EDP) problem, where one is given an undirected graph G and a set of terminal pairs P and asks whether G contains a set of …
Given an undirected graph $ G $ and a multiset of $ k $ terminal pairs $\mathcal {X} $, the Vertex-Disjoint Paths (\VDP) and Edge-Disjoint Paths (\EDP) problems ask whether $ G …
In this paper we revisit the classical edge disjoint paths (EDP) problem, where one is given an undirected graph G and a set of terminal pairs P and asks whether G contains a set of …

Amiri and Wargalla (2020) proved the following local-to-global theorem in directed acyclic graphs (DAGs): if $ G $ is a weighted DAG such that for each subset $ S $ of 3 nodes there …
The grid theorem, originally proved by Robertson and Seymour in 1986 [RS10, Graph Minors V], is one of the most central results in the study of graph minors and has found many …

We study the approximability of the All-or-Nothing multicommodity flow problem in directed graphs with symmetric demand pairs (SymANF). The input consists of a directed graph …

Structural parameters for undirected graphs such as the path-width or tree-width of graphs have played a crucial role in developing a structure theory for graphs based on the minor …
