Andreas Beham recently had to run some large parameter experiments in HeuristicLab - and by large we mean about 400 configurations per experiment and more than 27,000 individual runs. The goal of this experiment was to test several parameter configurations on a number of problem instances in order to find the configuration that performed best in those instances.

Andreas shares his thoughts on the design of large parameter experiments and how you can make them as memory-friendly as possible on the HeuristicLab Blog. The blog entry also comes with a helpful code sample that should get you starte...

We are very happy to announce that two long-term HEAL affiliates from the Institute for Production and Logistics Management at the Johannes Kepler University Linz have successfully defended their PhD theses. The orals were scheduled back to back on Tuesday with many friends and colleagues in the audience. Their individual research areas were:

• Roland Braune: Job Shop Scheduling with Total Weighted Tardiness Objective: Enhancements to Local Search and Bottleneck-based Methods.
• Michael Bögl: Suchraumstrukturanalysen und selbstlernende nachbarschaftsbasierte Suchverfahren am zeitfensterbeschränkt...

We are proud to announce that HEAL members have received the Best Paper Award of the 23rd European Modeling & Simulation Symposium (EMSS 2011) for their paper On the Use of Estimated Tumor Marker Classifications in Tumor Diagnosis Prediction!

In this paper recent research results in the area of medical data mining and modeling have been summarized. The paper was written by HEAL members Stephan Winkler, Michael Affenzeller, Gabriel Kronberger, Michael Kommenda, and Stefan Wagner in close collaboration with Prim. Dr. Herbert Stekel from the General Hospital Linz (AKH Linz) and Prof. Dr. Witold J...
