We are given a set P of points in the plane, together with a partition of P into classes of points; i.e., each point of P belongs to exactly one class. For a given network optimization problem, such as nding a minimum spanning tree or nding a minimum diameter spanning tree, we study the problem of choosing a subset P 0 of P that contains at least one point of each class and solving the network optimization problem for P 0 , such that the solution is optimal among all possible choices for P 0… CONTINUE READING
