Additional information  An instance of the singlerow facility layout problem is formally
defined by n onedimensional facilities with given positive lengths
and pairwise nonnegative weights. The objective is to arrange the
facilities so as to minimize the total weighted sum of the
centertocenter distances between all pairs of facilities. This
problem can be modeled as a quadratic objective over linear ordering
variables.
