Clear Consensus, Ambiguous Commitment

Ambiguous Language and Consensus∗

Standard economic models cannot capture the fact that information is often ambiguous, and is interpreted in multiple ways. Using a framework that distinguishes between the language in which statements are made and the interpretation of statements, we show that ambiguity can have important consequences. We show that players can agree to disagree in the presence of ambiguity, even if there is a c...

Continuous Consensus with Ambiguous Failures

Continuous consensus (CC) is the problem of maintaining an identical and up-to-date core of information about the past at all correct processes in the system [1]. This is a primitive that supports simultaneous coordination among processes, and eliminates the need of issuing separate instances of consensus for different tasks. Recent work has presented new simple and efficient optimum protocols ...

Group consensus peer review in radiation oncology: commitment to quality

BACKGROUND Peer review, especially prospective peer review, has been supported by professional organizations as an important element in optimal Radiation Oncology practice based on its demonstration of efficacy at detecting and preventing errors prior to patient treatment. Implementation of peer review is not without barriers, but solutions do exist to mitigate or eliminate some of those barrie...

On the Relationship Between the Atomic Commitment and Consensus Problems

Revisiting the Relationship between Non-blocking Atomic Commitment and Consensus ?

This paper discusses the relationship between the Non-Blocking Atomic Commitment problem (NB-AC) and the Consensus problem in asynchronous systems with unreliable failure detectors. We rst connrm that NB-AC is harder than Consensus. In contrast to Consensus , NB-AC is impossible to solve with unreliable failure detectors even with a single crash failure. We deene a weaker problem than NB-AC, ca...
