Almost Linear Time Computation of Maximal Repetitions in Run Length Encoded Strings

Abstract
We consider the problem of computing all maximal repetitions contained in a string that is given in run-length encoding.Given a run-length encoding of a string, we show that the maximum number of maximal repetitions contained in the string is at most m+k-1, where m is the size of the run-length encoding, and k is the number of run-length factors whose exponent is at least 2.
We also show an algorithm for computing all maximal repetitions in O(m \alpha(m)) time and O(m) space, where \alpha denotes the inverse Ackermann function.
