摘要

Quicksort 算法通常是排序的最佳实践选择,因为它在平均情况下具有显著的效率,θ(n log n) 符号中隐藏着较小的常数因子,而且具有就地排序的特性。本文对 Quicksort 算法及其变体进行了全面研究,并提供了实证结果。研究涵盖了 1961 年至今的所有 Quicksort 变体。此外,本文还比较了不同版本的 Quicksort 在整数数组上的运行时间,包括排序、反转和随机生成。对于任何有兴趣研究和了解 Quicksort 算法及其各种版本的人来说,我们的工作都是无价之宝。

Performance Analysis of Quicksort Algorithm: An Experimental Study of Its variants
The Quicksort algorithm is often the best practice choice for sorting due to its remarkable efficiency on average cases, small constant factors hidden in the θ(n log n) notation, and its in-place sorting nature. This paper provides a comprehensive study and empirical results of the Quicksort algorithm and its variants. The study encompasses all Quicksort variants from 1961 to the present. Additionally, the paper compares the performance of different versions of Quicksort in terms of running time on integer arrays that are sorted, reversed, and randomly generated. Our work will be invaluable to anyone interested in studying and understanding the Quicksort algorithm and its various versions.
