Exploring Unknown Environments
We consider exploration problems where a robot has to construct a complete map of an unknown environment. We assume that the environment is modeled by a directed, strongly connecte...

Better Bounds for Online Scheduling
We study a classical problem in online scheduling. A sequence of jobs must be scheduled on m identical parallel machines. As each job arrives, its processing time is known. The goa...

Pipelining with Futures
Pipelining has been used in the design of many PRAM algorithms to reduce their asymptotic running time. Paul, Vishkin, and Wagener (PVW) used the approach in a parallel implementat...

An Evaluation of VBR Disk Admission Algorithms for Continuous Media File Servers
In this paper, we address the problem of choosing a disk admission algorithm for continuous media streams where each stream may have a di erent bit rate, and more importantly, whe...

Evaluation of Linear Relations between Vectors of a Lattice in Euclidean Space
We prove that to find a nontrivial integer linear relation between vectors of a lattice L IRn , whose euclidean length is at most M, one needs O n5+ (ln Mn/)1+ binary operations f...

Safe BDD Minimization Using Don't Cares
In many computer-aided design tools, binary decision diagrams (BDDs) are used to represent Boolean functions. To increase the efficiency and capability of these tools, many algor...

Realistic Input Models for Geometric Algorithms
Many algorithms developed in computational geometry are needlessly complicated and slow because they have to be prepared for very complicated, hypothetical inputs. To avoid this, ...
