abstract = "In this paper we analyse the composition of the
function set of the artificial ant problem to define
new training and testing trails similar to the Santa Fe
trail. Cross-validation is used in applications where
large amounts of data are available. We also use a
semantically driven growth limiter to reduce program
size and check if growth reduction could lead to
increased test performance.",
