The Twelfth International Workshop on Learning Classifier Systems 
(IWLCS 2009) will be held in Montreal, Canada, Thursday, July 9, 2009 
during the Genetic and Evolutionary Computation Conference 
(GECCO-2009), July 8-12, 2009. 

Originally, Learning Classifier Systems (LCSs) were introduced by John 
H. Holland as a way of applying evolutionary computation to machine 
learning and adaptive behavior problems. Since then, the LCS paradigm 
has broadened greatly into a framework that encompasses many 
representations, rule discovery mechanisms, and credit assignment 
schemes. 

Current LCS applications range from data mining, to automated 
innovation and the on-line control of cognitive systems. LCS research 
includes various actual system approaches: While Wilson's accuracy-
based XCS system (1995) has received the highest attention and gained 
the highest reputation, studies and developments of other LCSs are 
usually discussed and contrasted. Advances in machine learning, and 
reinforcement learning in particular, as well as in evolutionary 
computation have brought LCS systems the necessary competence and  
guaranteed learning properties. Novel insights in machine learning and 
evolutionary computation are being integrated into the LCS framework. 

Thus, we invite submissions that discuss recent developments in all 
areas of research on, and applications of, Learning Classifier Systems. 
IWLCS is the event that brings together most of the core researchers 
in classifier systems. Moreover, a free introductory tutorial on LCSs 
is presented the day before the workshop at GECCO 2009. Tutorial and 
IWLCS workshop thus also provide an opportunity for researchers 
interested in LCSs to get an impression of the current research 
directions in the field as well as a guideline for the application of 
LCSs to their problem domain.


Submissions and Publication
---------------------------

Submissions will be short-papers up to 8 pages in ACM format. Please 
see the GECCO 2009 information for authors for further details.

All accepted papers will be presented at IWLCS 2009 and will appear in 
the GECCO workshop volume. Proceedings of the workshop will be 
published on CD-ROM, and distributed at the conference. Authors will 
be invited after the workshop to submit revised (full) papers for 
publication in the next post-workshop proceedings volume (scheduled 
for 2010), in the Springer LNCS/LNAI book series.

All papers should be submitted in PDF format and e-mailed to:
