For many years correlations between aspects of Artificial Immune Systems (AIS) and Learning Classifier Systems (LCS) have been highlighted. However, neither field appears to have benefitted from such work not least since the differences between the two approaches have far outweighed the similarities. More recently, a form of LCS has been presented for unsupervised learning which, with hindsight, may be viewed as a form of AIS. This paper aims to bring the aforementioned LCS to the attention of the AIS community with the aim of serving as a catalyst for the sharing of ideas and mechanisms between the two fields to mutual benefit. © 2011 Springer-Verlag.
