Dear All, 

We will have the following seminar by Michael T. M. Emmerich
(http://liacs.leidenuniv.nl/~emmerichmtm/), from LIACS, Leiden
University, on December 18th. 

Title:
Computational Geometry Challenges & Results in Multiobjective
Optimization

Date: 2017-Dec-18   Time: 14:30
Room: INESC-ID 020

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.

Short Biography:
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.
