For this reason, many algorithm designers concentrate on reducing the leading constant and on (implicitly) tailoring their algorithms to inputs typical to evolutionary computation. While doing that, they sometimes forget to ensure that the worst-case running time of their algorithm is still . This ...

As a byproduct of our study, we uncover a bug in the Java implementation that can cause the sorting method to fail during the execution. We also give a proof that Python's TimSort running time is in \mathcal{O}(n + n\log ho) \mathcal{O}(n + n\log ho) , where ho ho is ...
This means that they have to trust the mail server sending that email; in our case, that means the server used by the newsletter service. If that same server also happens to be sending out emails for other clients that are considered ‘spammy’, the deliverability of your own emails could...
We design main memory algorithms that sort in worst-case time such that the time varies smoothly from linear to optimal time for files that vary from being nearly sorted and have little disorder to being very unsorted. They are adaptive sorting algorithms. To this end, we...
In this paper I developed a Unidirectional Two-Way sorting algorithm, which out beats all other O(n2) sorting algorithms like Bubble sort, Cocktail sort, Selection sort and Insertion sort for average and worst cases. We also give a time complexity analysis of the algorithm. Major limitation of...
Analysis of algorithmsThe two most prominent solutions for the sorting problem are Quicksort and Mergesort. While Quicksort is very fast on average, Mergesort additionally gives worst-case guarantees, but needs extra space for a linear number of elements. Worst-case efficient in-place sorting, ...
