object BoundablePair
A pair of {link Boundable}s, whose leaf items support a distance metric between them. Used to compute the distance between the members, and to expand a member relative to the other in order to produce new branches of the Branch-and-Bound evaluation tree. Provides an ordering based on the distance between the members, which allows building a priority queue by minimum distance.
