Finding non-minority balls with majority and plurality queries

Combinatorics 2018-12-24 v1

Abstract

Given a set of nn colored balls, a \textit{majority, non-minority or plurality ball} is one whose color class has size more than n/2n/2, at least n/2n/2 or larger than any other color class, respectively. We describe linear time algorithms for finding non-minority balls using query sets of size qq of the following form: the answer to a majority/plurality query QQ is a majority/plurality ball in QQ or the statement that there is no such ball in QQ.
