GenX is a versatile program using the differential evolution algorithm for fitting X-ray and neutron reflectivity data. For simulating specular reflectivity GenX utilizes the Parratt recursion formula.The program is easily extensible, allowing users to incorporate their own models into the program. This can be useful for fitting data from other scattering experiments, or for any other minimization problem which has a large number of input parameters and/or contains many local minima, where the differential evolution algorithm is suitable. In addition, GenX manages to fit an arbitrary number of data sets simultaneously.What's New in This Release: [ read full changelog ]· Found a bug in the tof measurements for neutrons sigma and d had needed some truncation in order to get them working. Fixed.· Fixed a bug that occured in my bugfix in the Reflectivty plugin.· Fixed bug in the optimizer saving routines, appeared only on windows and mac.
