Naslov: Multi-Pivot Quicksort: Theory and Experiments

Povzetek:

Recently Vladimir Yaroslavskiy proposed a dual pivot quicksort algorithm that, contrary to prior theory and intuition, outperforms standard quicksort by a a significant margin under the Java JVM. More
recently, this algorithm has been analyzed in terms of comparisons and swaps by Wild and Nebel but failed to resolve the disagreement between theory and practice. We provide strong theoretical and practical evidence that cache behavior is causing most of the performance differences in these algorithms.

Lastly, we propose 3-pivot variant showing a 7-8% performance improvement over the previously best known quicksort algorithms.
