Open Generative Design is an initiative started by dr. Sivam Krish. The aim is to develop platform independent algorithms which can be used to browse through solution spaces of various parametric definitions. The algorithms will be written in Excel and special add-on will be developed for each parametric modeling package. The ones for Solidworks and Rhino Grasshopper are already available for download and others, including one for Generative Components are under development. Below you can listen to Sivam introducing the idea himself:

The first iteration of the Excel spreadsheet script will generate instances of parametric definitions which will be random but constrained by maximum and minimum values of each of the attributes. Further iterations will feature a variety of browsing algorithms. For now have a look at how it works with Solidworks:
