Abstract

Mergesort is one of the oldest and most venerable sorting algorithms and exists in many different flavors. In this short note we present yet another mergesort variant, queue-mergesort. We show that, like top-down mergesort but unlike bottom-up mergesort, this new variant performs an optimal number of comparisons in the worst case.
