An elementary proof that Herman ’ s Ring is ( N 2 )

Herman’s Ring [Inform. Process. Lett. 35 (1990) 63; http://www.cs.uiowa.edu/ftp/selfstab/H90.ps.gz] is an algorithm for selfstabilization of N identical processors connected uni-directionally in a synchronous ring; in its original form it has been shown to achieve stabilization, with probability one, in expected steps O(N2 logN). We give an elementary proof that the original algorithm is in fac...
