Hulls and Efficient Sets for the Rectilinear Norm

Given a set of points on the plane, we study the structure of their rectilinear hull. We also consider the multiple objective decision of identifying a facility location that minimizes the rectilinear distance to each of these points. We show specific correspondences between the efficient (non-dominated) solutions to the location problem and the rectilinear hulls of point sets in the plane.
