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 ...

Fast. Heap sort runs in time, which scales well as n grows. Unlike quicksort, there's no worst-case complexity. Space efficient. Heap sort takes space. That's way better than merge sort's overhead. Weaknesses: Slow in practice. While the asymptotic complexity of heap sort makes it...
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. ...
