WebbWith R. Morris's probabilistic counting, we can count up to a much larger value at the expense of some loss of precision. We let a counter value of i i represent that a count of n_i ni for i = 0, 1, \ldots, 2^b-1 i = 0,1,…,2b − 1, where the n_i ni form an increasing sequence of nonnegative values.
