abstract = "This paper presents evolutionary identification of a
particular form of behavioral laws for
elasto-visco-plastic materials termed rheological
models. First, rheologicalmodels with known graph of
connections are used, and the identification amounts to
identifying real-valued parameters. But the more
challenging task of identifying also thetopology of the
rheological model can be tackled using Genetic
Programming, after turning those models into
parse-trees. Both approaches are compared and discussed
ona simple artificial example.",
