About
Maintained by Patrick RoocksFirst published 2014-08-0413 releasesCRAN page ↗

Routines to select and visualize the maxima for a given strict partial order. This especially includes the computation of the Pareto frontier, also known as (Top-k) Skyline operator (see Börzsönyi, et al. (2001) doi:10.1109/ICDE.2001.914855), and some generalizations known as database preferences (see Kießling (2002) doi:10.1016/B978-155860869-6/50035-4).
