Generalized Consensus and Paxos
, 2005
"... Consensus has been regarded as the fundamental problem that must be solved to implement a fault-tolerant distributed system. However, only a weaker problem than traditional consensus need be solved. We generalize the consensus problem to include both traditional consensus and this weaker version. A ..."

General Consensus Protocols
- In Proc. of the 9th International Conference on Information Networking (ICOIN-9
, 1994
"... Distributed applications are realized by cooperation of multiple processes interconnected by communication networks. In the distributed applications, a group of processes have to make consensus. In this paper, we discuss a general model of consensus protocol which is composed of four steps, i.e. pre ..."

Fast genuine generalized consensus
- In SRDS 2011
"... Abstract-Consensus (agreeing on a sequence of commands) is central to the operation and performance of distributed systems. A well-known solution to consensus is Fast Paxos. In a recent paper, Lamport enhances Fast Paxos by leveraging the commutativity of concurrent commands. The new primitive, cal ..."

, called Generalized Paxos, reduces the collision rate, and thus the latency of Fast Paxos. However if a collision occurs, Generalized Paxos needs four communication steps to recover, which is slower than Fast Paxos. This paper presents FGGC, a novel consensus algorithm that reduces recovery delay when a
Sequence Logos: A New Way to Display Consensus Sequences
- Nucleic Acids Res
, 1990
"... INTRODUCTION A logo is "a single piece of type bearing two or more usually separate elements" [1]. In this paper, we use logos to display aligned sets of sequences. Sequence logos concentrate the following information into a single graphic [2]: 1. The general consensus of the sequences. ..."

Impossibility of distributed consensus with one faulty process
, 1983
"... The consensus problem involves an asynchronous system of proceses, some of which may be unreliable. The problem is for the rcliablc processes to agree on a bbary value. h this paper, it is shown that every protocol for this problem has the possibility of nontermination, even with only otre faulty p ..."

A New Extension of the Kalman Filter to Nonlinear Systems
, 1997
"... The Kalman filter(KF) is one of the most widely used methods for tracking and estimation due to its simplicity, optimality, tractability and robustness. However, the application of the KF to nonlinear systems can be difficult. The most common approach is to use the Extended Kalman Filter (EKF) which ..."

) which simply linearises all nonlinear models so that the traditional linear Kalman filter can be applied. Although the EKF (in its many forms) is a widely used filtering strategy, over thirty years of experience with it has led to a general consensus within the tracking and control community
Effective Erasure Codes for Reliable Computer Communication Protocols
, 1997
"... Reliable communication protocols require that all the intended recipients of a message receive the message intact. Automatic Repeat reQuest (ARQ) techniques are used in unicast protocols, but they do not scale well to multicast protocols with large groups of receivers, since segment losses tend to b ..."

. Despite the widespread use of error correcting codes in many fields of information processing, and a general consensus on the usefulness of FEC techniques within some of the Internet protocols, very few actual implementations exist of the latter. This probably derives from the different types
Wait-Free Synchronization
- ACM Transactions on Programming Languages and Systems
, 1993
"... A wait-free implementation of a concurrent data object is one that guarantees that any process can complete any operation in a finite number of steps, regardless of the execution speeds of the other processes. The problem of constructing a wait-free implementation of one data object from another lie ..."

lies at the heart of much recent work in concurrent algorithms, concurrent data structures, and multiprocessor architectures. In the first part of this paper, we introduce a simple and general technique, based on reduction to a consensus protocol, for proving statements of the form "
On Exploiting Locality for Generalized Consensus Alexandru Turcu Binoy Ravindran
"... Abstract-Single leader-based Consensus protocols are known to stop scaling once the leader reaches its saturation point. On the other hand, establishing Consensus of commands by taking into account only their dependencies (as specified by Generalized Consensus) is appealing because of the potential ..."

Agent-Based Product Configuration: towards Generalized Consensus Seeking

As a first step, we used the notion of consensus to establish robust results at the end of the configuration process. We implemented the concept of “generalized consensus ” which implied the ..."
