HeuristicLab 3.3.7 Release

Just in time for our tutorial at GECCO 2012, the HeuristicLab development team released HeuristicLab 3.3.7.

Among others, HeuristicLab 3.3.7 contains the following new features:

  • new dialog to automatically create large experiments
  • support for the optimization knowledge base (OKB)
  • new and improved implementation of the Vehicle Routing Problem (VRP) which supports more VRP variants such as CVRP, DCVRP, CVRPTW, PDPTW, and MDCVRPTW
  • lawn mower problem
  • linear assignment problem and Hungarian algorithm
  • benchmark problem instances: HeuristicLab now includes various libraries of published benchmark problem instances for combinatorial optimization problems (TSPLIB, QAPLIB, Taillard, Golden, Cordeau, Solomon, etc.) and regression/classification problems (Keijzer, Korns, Nguyen, real world problems, etc.)

HeuristicLab 3.3.6 Release

Happy new year! The HeuristicLab development team kicked off 2012 with the brand new HeuristicLab 3.3.6 release.

One of the most exciting new features of HeuristicLab 3.3.6 is HeuristicLab Hive which provides an infrastructure for parallel and distributed computing. Hive consists of a server and computation slaves. Users can upload jobs to the Hive server which distributes the jobs among the available slaves. The slaves execute the jobs and send the result back to the server after they are finished. More information about how to install a Hive server and Hive slaves and how to use Hive in general can be found in the Howtos?.

Additional new features in HeuristicLab 3.3.6 include:

  • Robust Taboo Search for the Quadratic Assignment Problem
  • New Standard Algorithms for Regression and Classification (kNN, Neural Networks, Multi-Nominal Logit Regression)
  • Genetic Programming Grammar Editor
  • New Standard Tree-Creation Operators for Genetic Programming (Grow, Full, Ramped Half-Half)
  • RunCollectionModifiers to Combine and Transform Algorithm Results
  • Improved Customization and Export of Charts
  • Performance Benchmarks
