Accelerating Matroid Optimization through Fast Imprecise Oracles

no code implementations5 Feb 2024 Franziska Eberle, Felix Hommelsheim, Alexander Lindermayr, Zhenwei Liu, Nicole Megow, Jens Schlöter

In the fundamental problem of computing a maximum-weight basis of a matroid, a well-known generalization of many combinatorial optimization problems, algorithms have access to a clean oracle to query matroid information.

Sorting and Hypergraph Orientation under Uncertainty with Predictions

no code implementations16 May 2023 Thomas Erlebach, Murilo Santos de Lima, Nicole Megow, Jens Schlöter

We study learning-augmented algorithms for sorting and hypergraph orientation under uncertainty, assuming access to untrusted predictions for the uncertain values.

Minimalistic Predictions to Schedule Jobs with Online Precedence Constraints

no code implementations30 Jan 2023 Alexandra Lassota, Alexander Lindermayr, Nicole Megow, Jens Schlöter

We consider non-clairvoyant scheduling with online precedence constraints, where an algorithm is oblivious to any job dependencies and learns about a job only if all of its predecessors have been completed.

Robustification of Online Graph Exploration Methods

no code implementations10 Dec 2021 Franziska Eberle, Alexander Lindermayr, Nicole Megow, Lukas Nölke, Jens Schlöter

Exploring unknown environments is a fundamental task in many domains, e. g., robot navigation, network security, and internet search.
