Merge Sort
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 ...
متن کاملParallel Algorithms and Structures for Implementation of Merge Sort
I. INTODACTION The development of information technologies is characterized by the expansion of applications, many of which requires parallel sorting of data sets in real-time. You can provide such data sorting by using of specialized tools, which architecture maps the structure of the sorting algorithm on hardware and is oriented on VLSI implementation. Implementation of highly efficient speci...

متن کاملModified Merge Sort Algorithm
Given a sequence of N elements a1, a2, a3, ..., aN. The desired output will be a’1, a’2, a’3,..., a’N such that a’1≤, a’2≤, a’3≤...≤a’N using merge sort. In this paper, we propose a modification to the existing merge sort algorithm to sort the given elements when the input sequence (or a part of it) is in ascending or descending order in a more efficient way by reducing the number of comparison...
متن کاملMerge 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...
