Approximating Some Network Design Problems with Node Costs
We study several multi-criteria undirected network design problems with node costs and lengths. All these problems are related to the Multicommodity Buy at Bulk (MBB) problem in w...

Approximation Schemes for Broadcasting in Heterogenous Networks
We study the problem of minimizing the broadcast time for a set of processors in a cluster, where processor has transmission time , which is the time taken to send a message to any...

Minimizing Error and VLSI Complexity in the Multiplication-Free Approximation of Arithmetic Coding
Two new algorithms for performing arithmetic coding without employing multiplication are presented. The first algorithm, suitable for an alphabet of arbitrary size, reduces the wo...

A 3-Approximation for Facility Location with Uniform Capacities
We consider the facility location problem where each facility can serve at most U clients. We analyze a local search algorithm for this problem which uses only the operations of ad...
