Editing Marzullo's algorithm (section)

{{Short description|Agreement algorithm}}
'''Marzullo's algorithm''', invented by [[Keith Marzullo]] for his Ph.D. dissertation in 1984, is an ''agreement algorithm'' used to select sources for estimating accurate time from a number of [[noise|noisy]] time sources. A refined version of it, renamed the "[[intersection algorithm]]", forms part of the modern [[Network Time Protocol]].
Marzullo's algorithm is also used to compute the [[relaxed intersection]] of n boxes (or more generally ''n'' subsets of '''R'''<sup>''n''</sup>), as required by several [[Set_estimation|robust set estimation]] methods.
