abstract = "We apply linear genetic programming to several
diagnosis problems in medicine. An efficient algorithm
is presented that eliminates intron code in linear
genetic programs. This results in a significant speedup
which is especially interesting when operating with
complex datasets as they are occuring in real-world
applications like medicine. We compare our results to
those obtained with neural networks and argue that
genetic programming is able to show similar performance
in classification and generalization even within a
relatively small number of generations.",
