Research Visit from Poland

P. FilipiakPatryk Filipiak, a junior lecturer at the Institute of Computer Science, University of Wroclaw (Poland), visited the CIplus research center in March. He is finalizing his PhD thesis concerning the behavior of “Proactive Evolutionary Algorithms in the Dynamic Constrained Optimization Problems” (DCOPs).
He proposed anticipation strategies that can speed up a convergence of candidate solutions in a class of DCOPs and applied these strategies to inverse kinematics problems. Patrick gave an interesting talk in SPOTSeven’s doctoral seminar. The beginning of his talk is shown in the following short video:

Results from the Cooperation Between University of British Columbia and Cologne University of Applied Sciences

Steven Ramage from University of British Columbia (UBC) describes the SPO development and the results from the cooperation between UBC and the SPOTSevenLab (Cologne University of Applied Sciences) as follows:

Experimental Methods

Results from the cooperation between UBC and SPOTSeven are published in the book “Experimental Methods for the Analysis of Optimization Algorithms”.

“Bartz-Beielstein et al. [2005] adapted EGO to the optimization of algorithms, with their Sequential Parameter Optimization (SPO) method. SPO uses the same acquisition functions as EGO, but a slightly different model, which includes a second order polynomial fit as well as the standard Gaussian process model. Unlike EGO, their approach is able to deal with random response values through a continual resampling of the best observed points using a doubling strategy, which allows the estimate to converge to the true value over time. Finally, as opposed to fitting the model with each sample point individually, as done by SKO, SPO merges the samples for each point into a better estimate of the objective at that point, and then fits the model on these merged estimates.
Hutter et al. [2009a] directly compared SPO and SKO and their suitability for algorithm configuration. They found that SPO in general outperformed SKO on the algorithms they studied. They also introduced SPO+, which introduced some modifications to the original algorithm….” Continue reading

Einladung zum Expertenseminar nach Brüssel

Screen Shot 2015-04-15 at 23.51.30Prof. Bartz-Beielstein wurde vom DAAD als Referent für das in Brüssel stattfindende europäische Expertenseminar “Dual Learning – Combining Practice-Orientated and Theoretical Learning in Higher Education” eingeladen. Im Rahmen dieses Seminars werden ca. 25-30 europäische Experten (insbesondere Vertreter aus den Ministerien der EU Mitgliedstaaten und der Ständigen Vertretungen in Brüssel) zusammenkommen, um sich zu den unterschiedlichen Formen der aus Praxis und Theorie kombinierten Studienprogrammen auszutauschen. Von deutscher Seite sollen sowohl die klassischen dualen Studiengänge, als auch Studiengänge, die in anderer strukturierter Form Praxis und Theorie miteinander verbinden, vorgestellt werden.
Von besonderem Interesse ist dabei die enge Verzahnung von Theorie und Praxis in den Studiengängen, zu der auch der Forschungsschwerpunkt CIplus durch seine vielfältigen Industriekontakte beiträgt. Ein Ziel des Seminar besteht darin, interessierten Partnerländern aufzuzeigen, welche unterschiedlichen Wege in der Einführung praxisorientierter Hochschulbildung gegangen werden können.


The 11th edition of the International Conference on Evolutionary and Deterministic Methods for Design, Optimization and Control with Applications to Industrial and Societal Problems, EUROGEN-2015, will be held at the University of Strathclyde, Glasgow (UK), 14-16 September, 2015.
Prof. Bartz-Beielstein accepted the invitation to serve as a Technical Advisory Panel member. Continue reading

Invitation to serve as a reviewer for the 2015 IEEE Congress on Evolutionary Computation

Prof. Dr. Bartz-Beielstein accepted the invitation to serve as a reviewer for the 2015 IEEE Congress on Evolutionary Computation (IEEE CEC2015) which will take place in Sendai, Japan.

The annual IEEE Congress on Evolutionary Computation is one of the leading events in the area of evolutionary computation. It covers all topics in evolutionary computation.
