Abstract
This paper studies two changes to XCS, a classifier
system in which fitness is based on prediction accuracy
and the genetic algorithm takes place in environmental
niches. The changes were aimed at increasing XCS's
tendency to evolve accurate, maximally general
classifiers and were tested on previously employed
"woods" and multiplexer tasks. Together the changes
bring XCS close to evolving populations whose
high-fitness classifiers form a near-minimal, accurate,
maximally general cover of the input and action product
space. In addition, results on the multiplexer, a
difficult categorization task, suggest that XCS's
learning complexity is polynomial in the input length
and thus may avoid the "curse of dimensionality", a
notorious barrier to scale-up. A comparison between XCS
and genetic programming in solving the 6multiplexer
suggests that XCS's learning rate is about three orders
of magnitude faster in terms of the number of input
instances processed.
