Learning-augmented query policies for minimum spanning tree with uncertainty

T Erlebach, MS de Lima, N Megow… - arxiv preprint arxiv …, 2022 - arxiv.org
We study how to utilize (possibly erroneous) predictions in a model for computing under
uncertainty in which an algorithm can query unknown data. Our aim is to minimize the …

An adversarial model for scheduling with testing

C Dürr, T Erlebach, N Megow, J Meißner - Algorithmica, 2020 - Springer
We introduce a novel adversarial model for scheduling with explorable uncertainty. In this
model, the processing time of a job can potentially be reduced (by an a priori unknown …

Query-competitive sorting with uncertainty

MM Halldórsson, MS de Lima - Theoretical Computer Science, 2021 - Elsevier
We study the problem of sorting under incomplete information, when queries are used to
resolve uncertainties. Each of n data items has an unknown value, which is known to lie in a …

Query minimization under stochastic uncertainty

S Chaplick, MM Halldórsson, MS de Lima… - Theoretical Computer …, 2021 - Elsevier
We study problems with stochastic uncertainty information on intervals for which the precise
value can be queried by paying a cost. The goal is to devise an adaptive decision tree to find …

Set Selection Under Explorable Stochastic Uncertainty via Covering Techniques

N Megow, J Schlöter - International Conference on Integer Programming …, 2023 - Springer
Given subsets of uncertain values, we study the problem of identifying the subset of
minimum total value (sum of the uncertain values) by querying as few values as possible …

Round-competitive algorithms for uncertainty problems with parallel queries

T Erlebach, M Hoffmann, MS de Lima - Algorithmica, 2023 - Springer
In computing with explorable uncertainty, one considers problems where the values of some
input elements are uncertain, typically represented as intervals, but can be obtained using …

Approximation Algorithms for k-Scenario Matching

D Blom, D Hyatt-Denesik, AJ Amelia… - … on Approximation and …, 2024 - Springer
Matching theory is among the most fundamental graph optimization problems. Several
different variants of this problem have been introduced and studied. Maximum matching …

Stochastic monotone submodular maximization with queries

T Maehara, Y Yamaguchi - arxiv preprint arxiv:1907.04083, 2019 - arxiv.org
We study a stochastic variant of monotone submodular maximization problem as follows. We
are given a monotone submodular function as an objective function and a feasible domain …

Optimization under explorable uncertainty: beyond the worst-case

J Schlöter - 2023 - media.suub.uni-bremen.de
When solving optimization problems that arise in real-world applications, uncertainty in the
input data and incomplete information are major challenges. Consider for example varying …
