PYGMALION

PyGMAlion (Plant Growth Model Analysis, Identification and Optimization) has become the leading development project in the group. The objective is on one hand to provide modelers with mathematical and statistical tools for model analysis, and on the other hand to capitalize in the same software the different methods developed in the group. The basic idea is that provided the modeler writes his dynamic system of plant growth in a simple frame (defining model state variables, state function, parameters, external inputs, and model observations) then some parameter estimation methods are available, as well as sensitivity analysis, evaluation of criteria for model selection and data assimilation.
