Abstract

Given a set of n elements each of which is either red or blue, it is known that in the worst case n - v(n) pairwise equal/not equal color comparisons are necessary and sufficient to determine the majority color, where v(n) is the number of 1-bits in the binary representation of n. We prove that 2n/3 - √8n/9π + O(logn) such comparisons are necessary and sufficient in the average case.
