| Additional information | An instance of the single-row facility layout problem is formally
defined by n one-dimensional facilities with given positive lengths
and pairwise non-negative weights. The objective is to arrange the
facilities so as to minimize the total weighted sum of the
center-to-center distances between all pairs of facilities. This
problem can be modeled as a quadratic objective over linear ordering
variables.
