From May 18 to May 20, 2026, Lennart Schäpermeier and Leonard Papenmeier from the Department of Information Systems participated in the COSEAL (Configuration and Selection of Algorithms) workshop at RWTH Aachen University. 

The workshop is a premier international event bringing together researchers from academia and industry across all areas of automated artificial intelligence (AutoAI). Participants discussed current advances and trends in the automated configuration and selection of algorithms, including automated machine learning (AutoML), Bayesian optimization, neural architecture search and automated algorithm selection. The latter was celebrated with a special session highlighting 50 years of algorithm selection research.

At this edition, Lennart Schäpermeier presented BONO-Bench, based on joint work with ERCIS member Pascal Kerschke, which was recently accepted at the ACM TELO journal (SJR Q1). BONO-Bench advances the state of the art in evaluating bi-objective optimization heuristics by providing a test suite with controllable challenges and reference solutions, enabling researchers to better understand and configure their optimization heuristics.

The COSEAL workshop series originally started in 2013 at the Department of Information Systems with a workshop organized by Prof. Dr. Heike Trautmann (ERCIS member, now University of Paderborn). It is held anually in locations across Europe and attracts approximately 100 participants from dozens of research institutes. Additionally, Lennart Schäpermeier (together with André Biedenkapp, University of Freiburg, and Theresa Eimer, University of Hannover), serves as a general chair of the COSEAL network.

The next COSEAL workshop is held from May 10-12, 2027 at TU Dortmund.
