MAGIX (Modelling and Analysis Generic Interface for eXternal numerical codes) is a model optimizer developed under the framework of the CATS (Coherent set of Astrophysical Tools for Spectroscopy) project, funded by the European ASTRONET. The goal is to use existing astrophysical models, and optimize their parameters to fit a given astrophysical data set. A number of algorithms can be used to explore the parameter space, to find the best-fitting values of the parameters to be optimized, and the corresponding confidence intervals. A GUI based frontend is being developed to make the registration of new models and creation/editing of new instances of initial conditions user-friendly. MAGIX complies with the data structures and reduction tools of ALMA (Atacama Large Millimeter Array), and is developed to be a tool accompanying observations assembled with the ALMA interferometer, but can be used on any, even non-astronomical, data sets.
