We are constantly working on new features to improve HeuristicLab, our framework for heuristic and evolutionary algorithms, as evident if you have a look at the change and ticket history on our development homepage http://dev.heuristiclab.com. However, we know that our wiki and issue tracking system can be a bit overwhelming.

The solution: Our brand new HeuristicLab Development Blog. The blog will allow our developers to post about new, exciting features they are working on, link to tutorials, teaching materials and additional goodies. We will of course still announce releases and important ne...

HEAL researchers Andreas Beham and Stefan Vonolfen are heading to Budapest, Hungary, on Wednesday to attend the 3rd IEEE International Symposium on Logistics and Industrial Informatics (LINDI 2011). We have been quite busy in the area of logistics and production optimization, as the titles of our accepted LINDI papers indicate:

• Solving Large-Scale Vehicle Routing Problem Instances Using an Island-Model Offspring Selection Genetic Algorithm
• A New Metric to Measure Distances between Solutions to the Quadratic Assignment Problem
• Re-Warehousing vs. Healing: Strategies for Warehouse Storage Locati...

Right on time for the upcoming GECCO Tutorial we have released HeuristicLab 3.3.5. Let us know what you think! New features include:

• Random forests (wrapper for ALGLIB implementation)
• Allele frequency analyzer for symbolic data analysis expression trees
• Optional caching and parallel execution of external evaluation results
• New analyzers and operators for the quadratic assignment problem (QAP)
• New tree view for experiments etc.
