Exploiting the Tradeoff Between Precision and Cpu-Time to Speed Up Nearest Neighbor Search
We describe a recursive algorithm to quickly compute the N nearest neighbors according to a similarity measure in a metric space. The algorithm exploits an intrinsic property of a...

Fault-Tolerant Clustering in Ad Hoc and Sensor Networks
In this paper, we study distributed approximation algorithms for fault-tolerant clustering in wireless ad hoc and sensor networks. A k-fold dominating set of a graph G = (V, E) is...

New Bounds for Motif Finding in Strong Instances
Many algorithms for motif finding that are commonly used in bioinformatics start by sampling r potential motif occurrences from n input sequences. The motif is derived from these s...

Virtual coordinates for ad hoc and sensor networks
In many applications of wireless ad hoc and sensor networks, position-awareness is of great importance. Often, as in the case of geometric routing, it is sufficient to have virtua...

Probabilistic Arc Consistency: A Connection between Constraint Reasoning and Probabilistic Reasoning
We document a connection between constraint reasoning and probabilistic reasoning. We present an algorithm, called probabilistic arc consistency, which is both a generalization of...
