  abstract =     "an evolutionary algorithm-based approach to model
                 selection and demonstrates its effectiveness in using
                 the information content of ecological data to choose
                 the correct model structure. Experiments with a
                 modified genetic algorithm are described that combine
                 parsimony with a novel gene regulation mechanism. This
                 combination creates evolvable switches that implement
                 functional variable-length genomes in the GA that allow
                 for simultaneous model selection and parameter fitting.
                 In effect, the GA orchestrates a competition among a
                 community of models. Parsimony is implemented via the
                 Akaike Information Criterion, and gene regulation uses
                 a modulo function to overload the gene values and
                 create an evolvable binary switch. The approach is
                 shown to successfully specify the correct model
                 structure in experiments with a nested set of
                 polynomial test models and complex biological
                 simulation models, even when Gaussian noise is added to
                 the data.",
