This dataset contains Generalized Feature Trees (GFTs) for several well-known feature models. A GFT is a representation of a feature model where all cross-tree constraints have been integrated directly into the feature tree structure itself, maintaining the semantics of the feature model (i.e., maintaining the same set of products). This refactoring eliminates explicit cross-tree constraints, allowing a feature to appear multiple times within the tree (in exclusive branches) to represent different valid configurations.
