Abstract
Genetic Programming (GP) is a machine learning
technique that was not conceived to use domain
knowledge for generating new candidate solutions. It
has been shown that GP can benefit from domain
knowledge obtained by other machine learning methods
with more powerful heuristics. However, it is not
obvious that a combination of GP and a knowledge
intensive machine learning method can work better than
the knowledge intensive method alone. In this paper we
present a multistrategy approach where an already
multistrategy approach (hamlet combines
analytical and inductive learning) and an evolutionary
technique based on GP (EvoCK) are combined for the task
of learning control rules for problem solving in
planning. Results show that both methods complement
each other, supplying to the other method what the
other method lacks and obtaining better results than
using each method alone.
