abstract = "Stock selection for hedge fund portfolios is a
challenging problem for Genetic Programming (GP)
because the markets (the environment in which the GP
solution must survive) are dynamic, unpredictable and
unforgiving. How can GP be improved so that solutions
are produced that are robust to non-trivial changes in
the environment? We explore an approach that uses
subsets of extreme environments during training.",

conference (GP-2007).
