Given a set S of n elements drawn from a linearly ordered set and a set K = {k1, k2, . . . , kr} of positive integers between 1 and n, the multiselection problem is to select the ki th smallest element for all values of i, 1 ≤ i ≤ r. We present an efficient randomised algorithm to solve this problem in time O(n log r) with probability at least 1−cn−1, where c is a positive constant.
