TimSort is an intriguing sorting algorithm designed in 2002 for Python, whose worst-case complexity was announced, but not proved until our recent preprint. In fact, there are two slightly different versions of TimSort that are currently implemented in Python and in Java respectively. We propose ...
m. Thus, if we store the results of all the calls during the computation and given that there can be at most n additions or maximum computations during a call of d(f, l), the complexity of the computation will be O(n 2.m). If Group Adaptative Routing is used, since we have to...

Also, MULTIFIT and dual approximation algorithm have been applied to this case and their worst-case performances have been analyzed [1], [10], [14]. It is not so difficult to see that the PTAS developed in [8], [7] can be applied to the case of the nonsimultaneous identical parallel...
The average complexity of any algorithm whatsoever under the universal distribution is of the same order of magnitude as the worst-case complexity. This holds both for time complexity and for space complexity. To focus our discussion, we use as illustrations the particular case of sorting ...
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 ...
We also give a time complexity analysis of the algorithm. Major limitation of the algorithm is that best case, average case and worst case behavior of the algorithm is same, that is there is no improvement in performance when the array is almost or already sorted.Satyender S. Duhan...
In this paper we prove that a recent algorithm for non-dominated sorting, called Filter Sort, has the worst-case complexity of . In particular, we present a scenario which requires Filter Sort to perform dominance comparisons, where each comparison, however, needs only O(1) elementary ...
