The Merge Sort is a well-known comparison-based sort algorithm that has the same time complexity for all cases and is not adaptive. In this paper we made some improvements on merging method of Merge Sort and present a new adaptive and merge based sort algorithm for nearl...
with a worst-case time complexity ofO(n log n). This means that regardless of the initial order of the elements in the array, Merge Sort will always take the same amount of time to sort an input of sizen.
Merge sort is arguably the first useful sorting algorithm you learn in computer science. Merge sort has a complexity of O(n log n), making it one of the more efficient sorting algorithms available. Additionally, merge sort is a stable sort (just like insertion sort) so that the relative or...

3. Best Case:This is when all the elements are already sorted, but still recursive calls are made thus, complexity is Θ(nlogn). And Complexity of Merge algorithm is O(n) in all cases. Thus Merge sort is a stable algorithm that uses O(n) of auxiliary space and Divides and Conquer ...
Merge sort was unique for its time in that the best, worst, and average time complexity are all the same:Θ(N*log(N)). This means an almost-sorted list will take the same amount of time as a completely out-of-order list. This is acceptable because the worst-case scenario, where a...
In an initial “pass” of all the records of the file (that we will call “pass 0”) we can consider a single page of the file at a time, load it into the main memory, sort its records using an efficient internal sorting algorithm (e.g. quick sort or merge sort), and then writ...
Since quicksort partitions to two memory regions, part of the loop can continue, reducing the wait time for cache line fetches. This gives an overall performance gain, even though the branchless operation is more expensive due to a lack of support for efficient branchless operations in C / ...
merge sort [′mərj ‚sȯrt] (computer science) To produce a single sequence of items ordered according to some rule, from two or more previously ordered or unordered sequences, without changing the items in size, structure, or total number; although more than one pass may be required...
