- The solution space is a consequence of those selections rather than a property of the situation, and the first frame's exclusions — fixed count, fixed candidate list, exogenous demand — are precisely the assumptions on which the adequacy of its answer depends.
This sourceTreats the absolute centre, which minimises the greatest distance to any point served, and the median, which minimises total distance, as two distinct objectives over the same network with distinct optima.
