abstract = "The bid-offer spread on equity options is a key source
of profits for market makers, and a key cost for those
trading in the options. Spreads are influenced by
dynamic market factors, but is there also a predictable
element and can Genetic Programming be used for such
prediction? We investigate a standard GP approach and
two optimisations age-layering and a novel crossover
operator. If both are beneficial as independent
optimisations, will they be mutually beneficial when
applied simultaneously? Our experiments show a degree
of success in predicting spreads, we demonstrate
significant benefits for each optimisation technique
used individually, and we show that when both are used
together significant detrimental over-fitting can
occur.",
