Delta-based Bidirectional Transformation

Traditional algebraic frameworks for bidirectional transformations are state-based: the input and output are states of data. But actual implementations are delta-based: the synchronizer tries to understand what is the delta resulted from the update, and then try to propagate the delta.

We show that state-based algebraic framework has several drawbacks, and build delta-based algebraic frameworks for both the asymmetric case and the symmetric case.
