In-place algorithmsSortingComputational complexityWe present an algorithm for asymptotically efficient sorting. Our algorithm sorts the given array A by the use of n·lgn + O(n·lg lgn) comparisons and O(n) element moves. Moreover, this algorithm works in-place, using only a constant auxiliary...
This shrinks the gap between the known information-theoretic lower bound and the existing algorithms to O(n·lg lgn) comparisons, even if we require the algorithm to use only a constant auxiliary memory and a linear number of moves.关键词: In-place algorithms Sorting Computational complexity ...

The sorting has to occur in-place. No additional files may be created I need to able to tell the progress. I display a progress bar of the sorting while it runs. Some amount of RAM may be used to speed up sorting. The amount will be passed as a parameter ...
O(n log n) in-place stable sorting is hard to achieve for sorting algorithms. Bubble Sort and Insertion Sort are stable and in-place but suboptimal. Efficient sorts, such as Quicksort and Heapsort, are in-place and O(n log n) but unstable. ...
As we see further on, stability has proven to be a critical attribute for the correctness of in-place merge algorithms. 1.2 A General Statement About Merging as it Relates to Sorting Merging is the process whereby two pre-sorted lists of m and n data values are combine in a systematic ...
It follows that the ("non in-place") algorithms developed by {\\\it I. Munro} and {\\\it P. M. Spira} [SIAM J. Computing 5, 1-8 (1976; Zbl 0324.68018)] for multisets are within $O(n)$ time optimal. Our improvement to the lower bound for sorting multisets also improves a lo...

摘要: We describe space-efficient algorithms for solving problems related to finding maxima among points in two and three dimensions. Our algorithms run in optimal O(n log n) time and occupy only constant extra space in addition to the space needed for representing the input....
Hi. Today I got an exam on "Algorithms and data structures" for people which learnt sorting month ago and there was a problem that neither me norMarcin_smuand few other good guys didn't solve and I'm interested in a solution, so maybe you can help?
