GECCO 2011: HeuristicLab Tutorial

With just a week to go until the GECCO 2011 conference, we would like to remind you that Stefan Wagner and Gabriel Kronberger will hold a HeuristicLab Tutorial there. In particular, they will show how to
  • parameterize and execute evolutionary algorithms to solve combinatorial optimization problems (traveling salesman, vehicle routing) as well as data analysis problems (regression, classification).
  • model custom optimization algorithms in the graphical algorithm designer.
  • setup a large scale optimization experiment and execute such experiments on multi‐core or cluster systems.
  • inspect executed test runs with HeuristicLab’s interactive charts for visual and statistical
  • extend HeuristicLab with your own problems or algorithms.

If you are attending GECCO it would be great to meet up!

Funded PhD Position: Exact Tracing of Evolutionary Search Trajectories in Complex Hypothesis Spaces

The Heuristic and Evolutionary Algorithms Laboratory at the Upper Austria University of Applied Sciences (Austria) offers a funded PhD position within the scope of the International PhD Program in Informatics Hagenberg. The group conducts scientific research in the field of metaheuristics for solving business, engineering, and biomedical problems.

The focus of the PhD research project should be to gain a better understanding of the evolutionary process by analyzing the search trajectories of genetic programming (GP) algorithms in different hypothesis spaces for academic as well as real-world data mining applications.

Recent algorithmic achievements like offspring selection in combination with linear scaling have enabled GP to achieve high quality results in system identification in less than 50 generations using populations with only several hundred individuals. Therefore the active gene pool of evolutionary search remains manageable and may be subjected to new theoretical investigations closely related to genetic programming schema theories, building block hypotheses and bloat theories.

We are seeking highly motivated and creative students with a master degree in Mathematics/Informatics or a related technical field. Prior knowledge about heuristic optimization and machine learning and programming experience with C# is a plus. Applications (including your CV, degree certificates, list of publications etc.) and informal queries about the lab and research projects should be addressed to Dr. Michael Affenzeller (, phone +43 (0)7236 3888-2031).

Further details about the PhD program can be found on

A longer, printable description of the PhD position as PDF document is also available.

Application Deadline: July 15th, 2011.

FFH 2011: Best Poster Award Runner-Up

Michael Affenzeller and Stefan Wagner represented HEAL at the 5th Austrian FH Research Forum (FFH 2011), which took place in Vienna from 27. to 28. April 2011. The aim of the event was to highlight recent scientific research conducted at Universities of Applied Sciences and network with fellow researchers, decision makers and business representatives. In total, 165 papers and posters from diverse research branches were presented at the forum. Our contribution, "HeuristicLab 3.3: An Extensible and Flexible Software System
for Heuristic Optimization", received the runner-up best poster award.

You can now download the poster.
