具有循环比较错误的排序

Sorting with Recurrent Comparison Errors

Barbara Geissmann, Stefano Leucci, Chih-Hung Liu, Paolo Penna

摘要:

我们提出了一个排序算法的情况下,经常性的随机比较错误。该算法基本上实现了同时良好的性能,以前的算法排序$n$不同的元素在这个模型中。特别地,它在$O(n^2)$时间中运行,输出中元素的最大位错是$O(\log n)$,而总位错是$O(n)$。这些保证是最好的可能,因为我们证明,即使是随机算法不能实现$o(\log n)$最大错位的高概率,或$o(n)$总错位的期望,无论其运行时间。

英文摘要:

We present a sorting algorithm for the case of recurrent random comparison errors. The algorithm essentially achieves simultaneously good properties of previous algorithms for sorting $n$ distinct elements in this model. In particular, it runs in $O(n^2)$ time, the maximum dislocation of the elements in the output is $O(\log n)$, while the total dislocation is $O(n)$. These guarantees are the best possible since we prove that even randomized algorithms cannot achieve $o(\log n)$ maximum dislocation with high probability, or $o(n)$ total dislocation in expectation, regardless of their running time.
