Taylor1plus[1] (or t1p) is an efficient implementation of the affine forms-based numerical abstract domain introduced by Eric Goubault and Sylvie Putot in [4].
It defines the meet operation of two affine sets as a logical product of standard zonotpes and boxes [2].
It also implements several join operations over such logical products.
All computations are enhanced using a (classical) product with the intervals-based abstract domain.
See [3] for a full account of the underlying theoretical developments (which are only partially implemented in t1p).
The domain requires the APRON library wrappers to work properly.
You can can also download it as part of APRON. Both copies are kept sync.
