Abstract

An (n, n/2)-selector is a comparator network that classifies a set of n values into two classes with the same number of values in such a way that each element in one class is at least as large as all of those in the other. Based on utilization of expanders, Pippenger[6] constructed (n, n/2)-selectors, whose size is asymptotic to 2n log₂ n and whose depth is O((log n)²). In the same spirit, we obtain a relatively simple method to construct (n, n/2)-seleetors of depth O(log n). We construct (n, n/2)-selectors of size at most 8n log ₂ n + O(n). Moreover, for arbitrary C > 3/log₂ 3 = 1.8927…, we construct (n, n/2)-selectors of size at most Cn log₂n + O(n).
