چکیده
Bingheng Wang Dept. of Computer Science Florida Institute of Technology Melbourne FL 32904 [email protected] ABSTRACT Given a list of elements, we rearrange the list with ascending or descending order. So far the existing approaches involve Bubble Sort, Insertion Sort, Selection Sort ( respectively in worst case) performing slow. Now we introduce a new algorithm Merge Sort to solve the problem with divide and conquer strategy. We prove the time complexity of Merge Sort is by theoretical evaluation and demonstrate the data of empirical evaluation for the better performance of merge sort compared with previous ones.

Merge Sort Algorithm
Given an array with n elements, we want to rearrange them in ascending order. Sorting algorithms such as the Bubble, Insertion and Selection Sort all have a quadratic time complexity that limits their use when the number of elements is very big. In this paper, we introduce Merge Sort, a divide-andconquer algorithm to sort an N element array. We evaluate the O(NlogN) time complexity of merge sor...
متن کاملKnitting Sort: A Novel Stable and Inplace Sorting Technique (An Extension of Exchange Sorting with Bitonic Sorting Network)
One of the most frequent operations performed on database is searching. To perform this operation we have different kinds of searching algorithms, some of which are Binary Search, Linear Search, Quadratic search[1], but these and all other searching algorithms work only on data, which are previously sorted. An efficient algorithm is required in order to make the searching algorithm fast and eff...
متن کاملList Sort: A New Approach for Sorting List to Reduce Execution Time
In this paper we are proposing a new sorting algorithm, List Sort algorithm, is based on the dynamic memory allocation. In this research study we have also shown the comparison of various efficient sorting techniques with List sort. Due the dynamic nature of the List sort, it becomes much more fast than some conventional comparison sorting techniques and comparable to Quick Sort and Merge Sort....
متن کاملA New Sorting Algorithm for Accelerating Join-based Queries
The performance of several Database Management Systems (DBMSs) and Data Stream Management Systems (DSMSs) queries is dominated by the cost of the sorting algorithm. Sorting is an integral component of most database management systems. Stable sorting algorithms play an important role in DBMS queries since such operations requires stable sorting outputs. In this paper, we present a new stable sor...
متن کاملEfficient unbalanced merge – sort q
Sorting algorithms based on successive merging of ordered subsequences are widely used, due to their efficiency and to their intrinsically parallelizable structure. Among them, the merge–sort algorithm emerges indisputably as the most prominent method. In this paper we present a variant of merge–sort that proceeds through arbitrary merges between pairs of quasi-ordered subsequences, no matter w...
