Recently, computer security has come to the forefront of public awareness. With the onslaught of worms such as Code Red, national (U.S.) concern has increased about cyber terrorism and the information infrastructure. One educational response has been the emergence of a number of computer security degree programs - at the undergraduate level, e.g., East… (More)

We give eecient algorithms to compute an optimal bipartition of a set of points or a set of simple polygons in the plane. In particular, we give an O(n 2) algorithm for partitioning a set of n points into two subsets in order to minimize the sum of the perimeters of the convex hulls. We also examine the problems of minimizing the maximum of the perimeters,… (More)

In this paper, we consider an optimal motion planning problem for a pair of point robots in a planar environment with polygonal obstacles. We seek a pair of paths upon which the robots can travel to move from their initial positions to positions in which they are able to communicate. In order to communicate, the robots need to be visible to one another. We… (More)
