Abstract: An Inexact Agreement protocol allows processors that each have a value approximating v to compute new values that are closer to each other and close to v . Two faulttolerant protocols for Inexact Agreement are described. As long as fewer than 1/3 of the processors are faulty, the protocols give the required convergence; they also permit iteration and thus convergence to any desired precision. When between 1/3 and 2/3 of the processors are faulty, the protocols may not converge. However, then... (Update)
