NDI (Download)

This implementation is based on the NDI algorithm (Calders and Goethals, 2002).

Several optimizations have been added, such as a fast algorithm for the inclusion-exclusion (see Calders and Goethals, KDID 2005).

The tar-ball contains the original breadth-first implementation, but also a depth-first implementation of the basic NDI algorithm (Calders and Goethals, SDM 2005). Note, however, that this depth-first implementation does not use the generalized diffsets as described in the latter paper.
