%description
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>).
