In modern distributed systems, failures are the norm rather than the exception. In many cases, these failures are not benign. Settings such as the Internet might incur malicious (also called Byzantine or arbitrary) behavior and asynchrony. As a result, and ...
Atomic Broadcast, an important abstraction in dependable distributed computing, is usually implemented by many instances of the well-known consensus problem. Some asynchronous consensus algorithms achieve the optimal latency of two (message) steps but cann ...
This paper presents an approach to automatic verification of asynchronous round-based consensus algorithms. We use model checking, a widely practiced verification method; but its application to asynchronous distributed algorithms is difficult because the s ...
The term distributed Consensus denotes the problem of getting a certain number of processes, that could be far away from each other and that exchange messages through some communication means, to all agree on the same value. This problem has been proved im ...
Problems in fault-tolerant distributed computing have been studied in a variety of models. These models are structured around two central ideas: Degree of synchrony and failure model are two independent parameters that determine a particular type of system ...
We provide a novel model to formalize a well-known algorithm, by Chandra and Toueg, that solves Consensus among asynchronous distributed processes in the presence of a particular class of failure detectors (Diamond S or, equivalently, Omega), under the hyp ...
We present a general framework and an efficient algorithm for tracking relevant video structures. The structures to be tracked are implicitly defined by a Matching Pursuit procedure that extracts and ranks the most important image contours. Based on the ra ...
Atomic broadcast is a useful abstraction for implementing fault-tolerant distributed applications such as state-machine replication. Although a number of algorithms solving atomic broadcast have been published, the problem of bounding the memory used by th ...

Uncertain information is commonplace in real-world data management scenarios. The ability to represent large sets of possible instances (worlds) while supporting efficient storage and processing is an important challenge in this context. The recent formali ...
