Near-Tight Runtime Guarantees for Many-Objective Evolutionary Algorithms

no code implementations19 Apr 2024 Simon Wietheger, Benjamin Doerr

This is the first time that such tight bounds are proven for many-objective uses of these MOEAs.

The Boundaries of Tractability in Hierarchical Task Network Planning

no code implementations25 Jan 2024 Cornelius Brand, Robert Ganian, Fionn Mc Inerney, Simon Wietheger

We study the complexity-theoretic boundaries of tractability for three classical problems in the context of Hierarchical Task Network Planning: the validation of a provided plan, whether an executable plan exists, and whether a given state can be reached by some plan.

Fair Correlation Clustering in Forests

no code implementations22 Feb 2023 Katrin Casel, Tobias Friedrich, Martin Schirneck, Simon Wietheger

To this end, we consider restricted graph classes which allow us to characterize the distributions of sensitive attributes for which this form of fairness is tractable from a complexity point of view.

Attribute Clustering +1

A Mathematical Runtime Analysis of the Non-dominated Sorting Genetic Algorithm III (NSGA-III)

1 code implementation15 Nov 2022 Simon Wietheger, Benjamin Doerr

In this work, we provide the first mathematical runtime analysis of the NSGA-III, a refinement of the NSGA-II aimed at better handling more than two objectives.

Maps for Learning Indexable Classes

no code implementations15 Oct 2020 Julian Berger, Maximilian Böther, Vanja Doskoč, Jonathan Gadea Harder, Nicolas Klodt, Timo Kötzing, Winfried Lötzsch, Jannik Peters, Leon Schiller, Lars Seifert, Armin Wells, Simon Wietheger

We study learning of indexed families from positive data where a learner can freely choose a hypothesis space (with uniformly decidable membership) comprising at least the languages to be learned.

Learning Languages with Decidable Hypotheses

no code implementations15 Oct 2020 Julian Berger, Maximilian Böther, Vanja Doskoč, Jonathan Gadea Harder, Nicolas Klodt, Timo Kötzing, Winfried Lötzsch, Jannik Peters, Leon Schiller, Lars Seifert, Armin Wells, Simon Wietheger

This so-called $W$-index allows for naming arbitrary computably enumerable languages, with the drawback that even the membership problem is undecidable.
