Given a finite set of points P in the Euclidean plane, the Steiner problem asks us to constuct a shortest possible network interconnecting P. Such a network is known as a minimal Steiner tree. The Steiner problem is an intrinsically difficult one, having been shown to be NP-hard [7]; however, it oft

β¦ Synopsis
We consider the problem of finding two sets of given cardinalities in certain grid graphs, so as to minimize the cross-distance between them. (This is the maximum Manhattan distance between points, one of the first set and another of the second set.) The question is answered completely for grids that are a product of chains of even edge length, and also for the (n)-cube, by way of the Clements-LindstrΓΆm approach.
