Conditions for tracking in networked control systems
— In this paper we obtain information theoretical conditions for tracking in linear time-invariant control systems. We consider the particular case where the closed loop contains...

Better Landmarks Within Reach
We study the real algorithm for the point-to-point shortest path problem. It combines A∗ search search, landmark-based lower bounds, and reach-based pruning. We suggest several ...

A multi-step strategy for approximate similarity search in image databases
Many strategies for similarity search in image databases assume a metric and quadratic form-based similarity model where an optimal lower bounding distance function exists for fil...

Improved Algorithms for Polynomial-Time Decay and Time-Decay with Additive Error
Abstract. We consider the problem of maintaining polynomial and exponential decay aggregates of a data stream, where the weight of values seen from the stream diminishes as time el...
