Diameter Computation on (Random) Geometric Graphs

Thomas Bläsius, Annemarie Schaub, Marcus Wilhelm

We present an algorithm that computes the diameter of random geometric graphs (RGGs) with expected average degree for constant in $\tilde{O}(n^{\frac{3}{2}(1+δ…

Structure and Independence in Hyperbolic Uniform Disk Graphs

Thomas Bläsius, Jean-Pierre von der Heydt, Sándor Kisfaludi-Bak +2

We consider intersection graphs of disks of radius in the hyperbolic plane. Unlike the Euclidean setting, these graph classes are different for different values of , where v…

Partitioning the Bags of a Tree Decomposition Into Cliques

Thomas Bläsius, Maximilian Katzmann, Marcus Wilhelm

We consider a variant of treewidth that we call clique-partitioned treewidth in which each bag is partitioned into cliques. This is motivated by the recent development of FPT-algor…

Deterministic Performance Guarantees for Bidirectional BFS on Real-World Networks

Thomas Bläsius, Marcus Wilhelm

A common technique to speed up shortest path queries in graphs is to use a bidirectional search, i.e., performing a forward search from the start and a backward search from the des…

From Symmetry to Asymmetry: Generalizing TSP Approximations by Parametrization

Lukas Behrendt, Katrin Casel, Tobias Friedrich +3

We generalize the tree doubling and Christofides algorithm, the two most common approximations for TSP, to parameterized approximations for ATSP. The parameters we consider for the…
