The Average-case complexity of determining the majority:

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...

Summary: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 - [square root] 8n/9[pi]+O(log n) such comparisons are necessary and sufficient in the average case."
