Parameterized Inapproximability of Independent Set in H-Free Graphs
We study the Independent Set problem in H-free graphs, i.e., graphs excluding some fixed graph H as an induced subgraph. We prove several inapproximability results both for polynomial-time and parameterized algor...

On Induced Online Ramsey Number of Paths, Cycles, and Trees
An online Ramsey game is a game between Builder and Painter, alternating in turns. They are given a fixed graph H and a an infinite set of independent vertices G. In each round Builder draws a new edge in G and P...

Parameterized Complexity of Length-bounded Cuts and Multicuts
We study the Minimum Length-Bounded Cut problem where the task is to find a set of edges of a graph such that after removal of this set, the shortest path between two prescribed vertices is at least ...

Local Structure Prediction with Convolutional Neural Networks for Multimodal Brain Tumor Segmentation
Most medical images feature a high similarity in the intensities of nearby pixels and a strong correlation of intensity profiles across different image modalities. One way of dealing with – and even exploiting...

Parametrized Complexity of Length-Bounded Cuts and Multi-cuts
We show that the minimal length-bounded \(L\) -cut can be computed in linear time with respect to
