Quantitative Research of Validity on Subsection Sorting Algorithm with Equal Probability Data Segment

This paper brings forward a subsection insertion sorting algorithm with equal probability data segment. The algorithm combines traditional sorting algorithms with some knowledge and skill of modern statistics to sort data with general distribution. The distribution information of these data is considered sufficiently. The approaches include mainly the following. Firstly, the distribution type of these data is determined experientially. Secondly, distribution parameters of these data are estimated. Thirdly, these data are assigned evenly to different segments on the whole. Finally, the data of different segments is sorted with traditional sorting algorithms. The complexity of this algorithm is limited to O(n) . And this paper uses the theory of non parametric hypothesis test to quantize the number of segments and approximate degree of distribution types and to deduce some factors which effect the number of segments and approximate degree of distribution types. Some important theoretic results are deduced. Let b represents the ratio of the number of data to the number of segments. Main results as follows. For larger number n , the algorithm is time optimal when b is a constant; the more approximate degree of distribution types is different, the value of b is to ensure the time complexity is O(n). This paper experimentalizes about these important results. Experiment results show that the theoretic results are consistent with practice.
