In-place sorting(原地排序):算法仅用固定内存完成排序,如快速排序。 In-place operations(原位操作):编程中直接修改对象而非生成新对象,例如Python列表的append()方法。 抽象引申 在管理中,“in-place system”指现行制度已成熟,无需重构;在学术领域,“in-place analysis”指基于现有数据的直...
SortingComputational 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 workspace. This ...
Fast stable in-place sorting e[with $O(n)$ data moves (eng) In this paper we give a positive answer to the long-standing problem of finding an in-place sorting algorithm performing $O(n\\log n)$ comparisons and $O(n)$ data moves in the worst case. So far, the better in-place...
we present the first known in-place suffix sorting algorithm, that is, our algorithm uses only O(1) workspace. The running time of our algorithmis O(nlog n) which is optimal in the general alphabet model since even sorting the n characters will ...
Algorithm Partitioning is analogous to sorting an array of 0's and 1's, where elements smaller than the pivot are 0 and elements larger are 1. (Munro et al. 1990) Logsort sorts 0's and 1's stably in O(n) time and O(log n) space via its partition. ...
A sort or merge algorithm is said to be in-place whenever it does sorting or merging with the use of constant extra memory. In this case, the amount of extra memory required to implement the algorithm does not depend on the number of records in the input list(s). In addition, the ...
We adapt heapsort for multisets and provide the first in-place algorithm for multisets that achieves the optimal bound up to lower order terms. We, then, obtain an optimal in-place algorithm to lexicographically sort an array of multidimensional vectors, by applying the multiset sorting algorithm ...

We show that we can improve the number of comparisons if we sort blocks of constant length with Merge-Insertion, before starting the algorithm. Another improvement is to start the iteration with a better version, which needs only (1+ε)nspace and again additionalO(n)transports. The result is...
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?
