Habilitation Stephan Winkler

We are very proud to announce, that our long-time colleague Stephan Winkler finished his habilitation at the Johannes Kepler University in Linz.

This is a huge success not only for him, but also for the research group HEAL and gives us new perspectives in researching and supervising theses!


Big in Japan - GECCO Conference 2018

At this year's Genetic and Evolutionary Computation Conference (GECCO) in Kyoto, our research group was again represented with a large delegation of experienced and young researchers. The GECCO Conference is one of the most important and prestigious conferences for the latest high-quality results in genetic and evolutionary computation since 1999.

We are very proud, that this year four of our contributions were accepted in one of the main tracks!

Besides the EvoSoft workshop hosted by Stefan Wagner and Michael Affenzeller several of our researchers held workshops, paper and poster presentations:

·         Gabriel Kronberger presented „Predicting Friction System Performance with Symbolic Regression and Genetic Programming with Factor Variables“ 

·         Andreas Beham presented "Algorithm Selection on Generalized Quadratic Assignment Problem Landscapes"

·         Michael Affenzeller held an invited talk about "Data-Based Modeling and Optimization in Industrial Processes" in the  "Evolutionary Computation in Practive (ECip)" track organized by Thomas Bartz-Beielstein

·         Johannes Karder presented the paper "Asynchronous Surrogate-assisted Optimization Networks" 

·         Sebastian Raggl presented "Discrete Real-world Problems in a Black-box Optimization Benchmark​"

·         Bogdan Burlacu presented a part of his PhD thesis, finished with distinction in 2017, under the title "Schema-based Diversification in Genetic Programming"

·         Bernhard Werth presented the paper entiteled "Quasi-Bistability of Walk-Based Landscape Measures in Stochastic Fitness Landscape" 

·         Lukas Kammerer discussed his poster "Confidence-Based Ensemble Modeling in Medical Data Mining"

​Also some of our former research group members and graduates like Roland Braune (University of Vienna), Stefan Forsterlechner (University of Dublin) or Ciprian Zavoianu (Johannes Kepler University Linz) are successfully represented at the GECCO Conference. 


Around 700 researchers participated at the conference in Kyoto - they made this year's conference the second largest GECCO ever.

Dr. Michael Kommenda - Congratulations!

We would like to congratulate our colleague Michael Kommenda who successfully defended his PhD thesis! Michael is one of our longest researchers and joined HEAL in 2008. He has done his PhD-thesis "Local Optimization and Complexity Control for Symbolic Regression" at the JKU - supervised by FH-Prof. PD DI Dr. Michael Affenzeller and a.Univ.Prof Dr. Josef Küng.

"New ways of managing slab processing"

Our company partner voestalpine authors a own blog lately and in one of their articles they published the output of the K-Project HOPL in slab processing. 

Under the title " New ways of managing slab processing" they wrote an article about the innovative digital technologies that are being applied to manage slab processing at the Steel Division in Linz.

Gabriel Kronberger received Researcher Award 2017

The Upper Austria University of Applied Sciences (FH OÖ) honors outstanding scientists and scholars actively engaged in research in an annual award ceremony. We are delighted to announce that a prize went also to our research team this year: Gabriel Kronberger received the Researcher Award 2017 for his contributions to the field of Business Intelligence and Data Engineering. Congratulations!

Michael Affenzeller & Stefan Wagner at IWMMA conference 2017 in Krasnoyarsk

Michael Affenzeller and Stefan Wagner were invited to hold a keynote and a HeuristicLab-tutorial at the IWMMA conference in Krasnoyarsk, Russia - The Sixth International Workshop on Mathematical Models and their Applications​. 

The Sixth International Workshop on Mathematical Models and their Applications (IWMMA 2017) will provide an international forum for the presentation of original results in mathematical modeling for software- and hardware applications in various fields. It will stimulate lively discussions among researchers as well as industrialists.

Michael Affenzeller's keynote titled "Real-World Systems Modeling and Optimization with Hybrid Evolutionary Algorithms" - The focus of the talk was on systems modeling, optimization, algorithm design and analysis with respect to real world problems using different flavors of evolutionary algorithms. A special focus was on the analysis of algorithm dynamics in order to analyze the reasons of premature convergence which provides deeper insights about the algorithms internal behavior and gives inspiration for the design of new hybrid algorithms.

Stefan Wagner's tutorial titled "Algorithm and Experiment Design with HeuristicLab. An Open Source Optimization Environment for Research and Education" - This tutorial demonstrated how to apply and analyze metaheuristic optimization algorithms using the HeuristicLab open source optimization environment. It was shown how to parameterize and execute evolutionary algorithms to solve various optimization problems (e.g., traveling salesman, vehicle routing, quadratic assignment, symbolic regression).

Thanks to Eugene Semenkin and his team for the invitation and the interesting feedback to the keynote and the tutorial!

Dr. Bogdan Burlacu - Congratulations!

Dr. Bogdan Burlacu

We would like to congratulate our colleague Bogdan Burlacu who successfully defended his PhD thesis yesterday! Bogdan joined us a couple of years ago and is doing research in genetic programming. He has done his PhD within the international PhD program jointly organized by JKU and FH Upper Austria and finished his PhD studies with distinction.

The best of both worlds: Combining the Flexibility of Modeling & Simulation with Optimization by Evolutionary Algorithms

Michael Affenzeller as keynote speaker at the I3M conference in Barcelona!

Every year, the I3M Multiconference renovates the opportunity to bring together researchers, scientists and practitioners, from the Mediterranean Area, Latin & North Americas, Europe, Asia, Africa and Australia, who are concerned with Modeling and Simulation in Industry and Academia.

Affenzeller's presentation will cover theoretical aspects as well as real world examples demonstrating how the open source framework HeuristicLab can be used for modeling, optimization and machine learning tasks for concrete challenges in the domain of production, logistics and systems research.

Evolutionary Algorithms Pioneer Nic McPhee visiting Hagenberg campus

We are glad to announce that Nicolas Freitag McPhee from the University of Minnesota, Morris visited our campus after the Berlin GECCO giving many valuable hints to Patrik Kimmeswenger, who is implementing PushGP in HeuristicLab in his master thesis. Nic McPhee has authored and co-authored many relevant publications especially in the field of genetic programming like the field guide to genetic programming; his recent research interests include the analysis of GP ancestry which brought us in contact as our colleague Bogdan Burlacu has also been working in this field over the last years within the scope of his PhD thesis and has spent a research visit in Morris last year.
