Abstract: Propose the grouping sort algorithm,and labor it’s principle and complexity of time and space.Obtain that it’s time complexity is θmn) in the worst situation,and it’s time complexity of is θnlog(n/mk)) in the best or in average situation.Obtain that it’s complexity of space is O(mn-m2m) in the worst situation,and it’s complexity of space is O(mklog(n/mk)) in the best or in average situation.Take the experiment with the multi-group random data.The result shows the article’s correctness.This result is very helpful for designing efficient algorithms for huge data processing.

Key words: sort, group sort, quick sort, merge sort, radix sort

摘要: 提出了分组排序算法,详细分析了算法的原理及其时间与空间复杂度,得出了在最坏情况下的时间复杂度是θmn);最好情况和平均情况下的时间复杂度均是θnlog(n/mk));在最坏情况下的空间复杂度是O(mn-m2m);最好情况和平均情况下的空间复杂度均是O(mklog(n/mk));并用多组随机数据与效率较高的快速算法进行仿真对比实验,试验结果说明了文中结论的正确性。这一结果,将有助于进一步设计高效的海量数据分析方法。
