The agenda for the Ninth International Workshop on Learning Classifier Systems (IWLCS’2006) can be found here. The workshop is coming with a list of very interesting papers and topics. We are looking forward to another edition of the workshop crowded of new and exiting ideas. If you are in GECCO, do not let it pass by ;). By the way, if you want to dig a little further into the learning classifier systems (LCS) and other genetics-based machine learning (GBML) world, check the website of the NCSA/IlliGAL Gathering on Evolutionary Learning (NIGEL’2006). It contains the slides and videos of the talks on cutting-edge LCS and GBML research.
