From Performance to Understanding: A Vision for Explainable Automated Algorithm Design

Niki van Stein, Anna V. Kononova, Thomas Bäck

Automated algorithm design is entering a new phase: Large Language Models can now generate full optimisation (meta)heuristics, explore vast design spaces and adapt through iterativ…

Lost in Vagueness: Towards Context-Sensitive Standards for Robustness Assessment under the EU AI Act

Roberta Tamponi, Carina Prunkl, Thomas Bäck +1

Robustness is a key requirement for high-risk AI systems under the EU Artificial Intelligence Act (AI Act). However, both its definition and assessment methods remain underspecifie…

DQS: A Low-Budget Query Strategy for Enhancing Unsupervised Data-driven Anomaly Detection Approaches

Lucas Correia, Jan-Christoph Goos, Thomas Bäck +1

Truly unsupervised approaches for time series anomaly detection are rare in the literature. Those that exist suffer from a poorly set threshold, which hampers detection performance…

Behaviour Space Analysis of LLM-driven Meta-heuristic Discovery

Niki van Stein, Haoran Yin, Anna V. Kononova +2

We investigate the behaviour space of meta-heuristic optimisation algorithms automatically generated by Large Language Model driven algorithm discovery methods. Using the Large Lan…

Reasoning Capabilities of Large Language Models on Dynamic Tasks

Annie Wong, Thomas Bäck, Aske Plaat +2

Large language models excel on static benchmarks, but their ability as self-learning agents in dynamic environments remains unclear. We evaluate three prompting strategies: self-re…

BLADE: Benchmark suite for LLM-driven Automated Design and Evolution of iterative optimisation heuristics

Niki van Stein, Anna V. Kononova, Haoran Yin +1

The application of Large Language Models (LLMs) for Automated Algorithm Discovery (AAD), particularly for optimisation heuristics, is an emerging field of research. This emergence…

Optimizing Photonic Structures with Large Language Model Driven Algorithm Discovery

Haoran Yin, Anna V. Kononova, Thomas Bäck +1

We study how large language models can be used in combination with evolutionary computation techniques to automatically discover optimization algorithms for the design of photonic…

Code Evolution Graphs: Understanding Large Language Model Driven Design of Algorithms

Niki van Stein, Anna V. Kononova, Lars Kotthoff +1

Large Language Models (LLMs) have demonstrated great promise in generating code, especially when used inside an evolutionary computation framework to iteratively optimize the gener…

Abnormal Mutations: Evolution Strategies Don't Require Gaussianity

Jacob de Nobel, Diederick Vermetten, Hao Wang +3

The mutation process in evolution strategies has been interlinked with the normal distribution since its inception. Many lines of reasoning have been given for this strong dependen…
