heapsort在实践中的表现经常不如quicksort(尽管quicksort最差表现为 \(\Theta (n^2)\),但quicksort 99%情况下的runtime complexity为 \(\Theta (nlgn)\)),但heapsort的\(O(nlgn)\)的上限以及固定的空间使用经常被运作在嵌入式系统。在搜索或机器学习中经常也有重要的作用,它可以只返回k个排序需要的值而不...
In this paper we present a generalized heapsort algorithm and its worst-case complexity analysis. The weighted sum of the number of comparisons and movements has been defined as a measure of the complexity. Theoretical analysis suggests that, by this criterion, 3-heap should be optimal in the ...

Heap Sort is an efficient, comparison-based sorting algorithm that uses a binary heap data structure to sort elements. It combines the speed of Quick Sort with the consistent performance of Merge Sort, making it an excellent choice for systems requiring guaranteed O(n log n) time complexity. ...
The experiment certifies that the time property of the new algorithm is superior to that of the best in-place heapsort.───实验表明,新算法的时间性能优于目前最好的原地排序一堆排序。 Improved heapsort algorithm and its complexity analysis───改进的堆排序算法及其复杂度分析 An Algorithm Study ...
Fast. Heap sort runs in O(nlg(n))O(nlg(n)) time, which scales well as nn grows. Unlike quicksort, there's no worst-case O(n2)O(n2) complexity. Space efficient. Heap sort takes O(1)O(1) space. That's way better than merge sort's O(n)O(n) overhead. Weaknesses: ...
The similarities with insertion sort include that only a constant number of array elements are stored outside the input array at any time.The time complexity of the heap sort algorithm is O(nlogn), similar to merge sort.ExampleLet us look at an example array to understand the sort algorithm...
