The Parameterized Complexity of Coordinated Motion Planning

no code implementations12 Dec 2023 Eduard Eiben, Robert Ganian, Iyad Kanj

The goal is to compute a schedule for moving the $k$ robots to their destinations which minimizes a certain objective target - prominently the number of time steps in the schedule, i. e., the makespan, or the total length traveled by the robots.

The Computational Complexity of Concise Hypersphere Classification

no code implementations12 Dec 2023 Eduard Eiben, Robert Ganian, Iyad Kanj, Sebastian Ordyniak, Stefan Szeider

Hypersphere classification is a classical and foundational method that can provide easy-to-process explanations for the classification of real-valued and binary data.

Optimal Streaming Algorithms for Graph Matching

no code implementations13 Feb 2021 Jianer Chen, Qin Huang, Iyad Kanj, Ge Xia

For the dynamic streaming model, we present a one-pass algorithm that, with high probability, computes a maximum-weight $k$-matching of a weighted graph in $\tilde{O}(Wk^2)$ space and that has $\tilde{O}(1)$ update time, where $W$ is the number of distinct edge weights and the notation $\tilde{O}()$ hides a poly-logarithmic factor in the input size.

The Parameterized Complexity of Cascading Portfolio Scheduling

no code implementations NeurIPS 2019 Eduard Eiben, Robert Ganian, Iyad Kanj, Stefan Szeider

Cascading portfolio scheduling is a static algorithm selection strategy which uses a sample of test instances to compute an optimal ordering (a cascading schedule) of a portfolio of available algorithms.

Local Backbones

no code implementations19 Apr 2013 Ronald de Haan, Iyad Kanj, Stefan Szeider

The empirical results we obtain show that a large fraction of the backbones of structured SAT instances are local, in contrast to random instances, which appear to have few local backbones.
