Computational Geometry Challenges and Results in Multiobjective Optimization

Michael Emmerich,
U – Leiden University –
Abstract:
In multiobjective optimization and decision analysis, it is common to compute sets of points or polytopes that cover trade-off (hyper)surfaces. In this talk, we will look at computational geometry problems related to this and their computational complexity. Many of these results have been discovered very recently and show that the boundary between the computational problems that are tractable and intractable depends on various parameters and is very sensitive to the number of objectives.
Bio
Michael T. M. Emmerich is Associate Professor at LIACS, Leiden University is an expert in indicator-based multicriteria optimization, decision analysis, and complex network research. He is the leader of the Multicriteria Optimization and Decision Analysis (MODA) research group at LIACS – the computer science department of Leiden University. He received his doctor in the natural sciences (Dr.rer. nat.) from the Informatics Department of the Technical University of Dortmund. He successfully carried out projects as a research consultant with ICD e.V. (Germany), ACCESS e.V., RWTH Aachen, IST Lisbon, University of the Algarve (Portugal), Princeton University, and the FOM/AMOLF Institute on Fundamental Science of Matter (Amsterdam, Netherlands). He is an editorial board member of the MIT Journal on Evolutionary Computation and Steering Committee member in the EMO and EVOLVE conference series. Michael Emmerich has co-authored more than 120 articles in peer-reviewed journals and conferences. He has been general chair of three international Lorentz Centre workshops on multicriteria optimiation and one international conference on set-oriented numerics. At LIACS he is the coordinator of the European Research Center on Information Systems (ERCIS) and member of the International Society on Multicriteria Decision Analysis.

The 13th Lisbon Machine Learning School | LxMLS 2023

The Lisbon Machine Learning Summer School (LxMLS) takes place yearly at Instituto Superior Técnico (IST). LxMLS 2023 will be a 6-day event (14-20 July, 2023), scheduled to take place as an in-person event.
The school covers a range of machine learning topics, from theory to practice, that are important in solving natural language processing problems arising in different application areas. It is organized jointly by Instituto Superior Técnico (IST), a leading Engineering and Science school in Portugal, the Instituto de Telecomunicações, the Instituto de Engenharia de Sistemas e Computadores, Investigação e Desenvolvimento em Lisboa (INESC-ID), the Lisbon ELLIS Unit for Learning and Intelligent Systems (LUMLIS), Unbabel, Zendesk, and IBM Research.
Check online for information about past editions: LxMLS 2011, LxMLS 2012, LxMLS 2013, LxMLS 2014, LxMLS 2015, LxMLS 2016, LxMLS 2017, LxMLS 2018, LxMLS 2019, LxMLS 2020, LxMLS 2021, LxMLS 2022 (you can also watch the videos of the lectures for 2016, 2017, 2018, and 2020).
31st International Conference on Information Systems Development (ISD 2023)

The 31st International Conference on Information Systems Development (ISD 2023) conference provides a forum for research and developments in the field of information systems. The theme of ISD 2023 is “Information systems development, organizational aspects and societal trends”. New trends in developing information systems emphasize the continuous collaboration between developers and operators in order to optimize the software delivery time. The conference promotes research on methodological and technological issues and how IS developers and operators are transforming organizations and society through information systems.
The ISD 2023 conference held this year also provides an opportunity for researchers and practitioners to promote their research, practical experience, and to discuss issues related to Information Systems through papers, posters, and journal-first paper presentations.
ISD 2023 will be hosted by Instituto Superior Técnico, in Lisbon, Portugal, on August 30–September 1, 2023.
