Bottom-Up-Heapsort is a variant of Heapsort. Its worst case complexity for the number of comparisons is known to be bounded from above by 3/2 n log n+O(n) , where n is the number of elements to be sorted. There is also an example of a heap which needs 5/2 n log nO(n log...
Bottom-Up-Heapsort is a variant of Heapsort. Its worst-case complexity for the number of comparisons is known to be bounded from above by 3/2n logn+0(n), wheren is the number of elements to be sorted. There is also an example of a heap which needs 5/4n logn-0(n log logn) com...

How do you determine the size of a matrix in Python? Consider Algorithm COUNT4 whose input is a positive integer n. (a) How many times Step 6 is executed? (b) Which one of the following and notations is more appropriate to express the time complexity o Wh...
d-heapsortIn 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 ...
Bottom-Up-Heapsort is a variant of Heapsort. Until now, its worst case complexity for the number of comparisons has been known to be bounded above by 1.5n log n + 0(n), where n is the number of elements to be sorted; but it was conjectured to be n log n + o(n log n). ...
First we present a new variant of Merge-sort, which needs only 1.25n space, because it uses space again, which becomes available within the current stage. It does not need more comparisons than classical Merge-sort. The main result is an easy to implemen
We investigate the complexity of constructing heaps. The heap construction problem has been extensively studied. However, there was no algorithm for building heaps that is optimal in both the worst and average cases simultaneously . In particular, the worst-case fastest algorithm, proposed by Gonnet...
