abstract = "Genetic programming (GP) approaches have been widely
studied for symbolic regression problems and have
achieved substantial progress. This work investigates
the effectiveness of niching property and multiple
learnt solutions of a Learning Classifier System (LCS)
to symbolic regression benchmark problems.
Specifically, an XCS with real-valued interval based
conditions and code fragmented action termed as XCS-SR
is proposed for tackling symbolic regression problem.
This is the first LCS ever to address the problem of
symbolic regression. The results on nine standard
symbolic regression benchmarks show that the proposed
XCS-SR method consistently obtains statistically better
results on a majority of the benchmarks, in terms of
average absolute error together with an increased
number of exact solutions as compared with the GP
benchmark.",
