Computational geometry emerged from the sector of algorithms layout and research within the past due Seventies. It has grown right into a well-known self-discipline with its personal journals, meetings, and a wide group of energetic researchers. The luck of the sector as a study self-discipline can at the one hand be defined from the great thing about the issues studied and the options received, and, nevertheless, by means of the various software domains---computer portraits, geographic details platforms (GIS), robotics, and others---in which geometric algorithms play a basic function.

Example text

In fact, even for a very restricted case on a 3-regular Hamiltonian network, no algorithm can guarantee a constant approximation better than 2. We then present a simple algorithm that guarantees an O(log n)- and O(log K)-approximation for arbitrary networks, where n is the number of nodes in the network and K is the number of demands. 2 we focus on the ring topology. Rings are of particular interest since often the underlying infrastructure is a ring for metro-area networks. We give a 3/2-approximation.

G. [22,3]. The model for VPL differs from ours in several aspects. For example, our line systems form a partition of the network links whereas virtual paths are allowed to overlap. Also, our demand routes can enter and depart from any point along a line system whereas demand routes for VPL have to be concatenations of entire virtual paths. This makes a huge difference in the model, since the extra constraint that all routes must be concatenations of whole line systems can increase the optimal solution by a factor of K.

A routing path of a demand consists of one or more transparent sections, where each transparent section is the intersection of the routing path and a line system. It is worth pointing out here that if multiple units of demand switch from one line system to another, each demand unit requires its individual O-E-O converter. Therefore, our objective is minimizing the total number of transparent sections summed over all demands, which is equivalent to minimizing the network equipment cost and minimizing O-E-O conversions.
