Webuse of techniques developed in studying Byzantine Agreement, is Approximate Agreement, introduced in [DLPSW]. In that paper algorithms were given for both synchronous and … Webwhile retaining optimal resilience and polynomial message complexity. The algorithm by Berman et al. [6] is well known as the king algorithm and is still commonly used [22], [12], [1]. The approximate agreement algorithm was introduced by Dolev et al. [13] and is a useful primitive in designing distributed algorithms [24], [14].It also requires ...
WebIn [DLPSW] the algorithms given are shown to be optimal (for Byzantine faults) among algorithms having thesame form, that is, where value chosen in each round depends only on values held by processors at the start of that round.
