These algorithms are important and have been an area of focus for a long time but still the question remains the same of "when to use which algorithm?" which is the main reason to perform this research. Each al
Divide-and-conquer algorithms: The divide-and-conquer algorithm is an effective algorithm that works by recursively breaking down a problem into two or more subproblems of the same or related type until these become simple enough to be solved directly and rather easily. ...
We take care that these allocation steps do not cause any unbalanced distribution of work, and that, asymptotically, they do not increase the running time. Variants of our generic algorithm also work for the butterfly network and, by a general simulation, for the class of hypercubic networks,...

Divide-and-conquer algorithm - Wikipediaen.wikipedia.org/wiki/Divide-and-conquer_algorithm The divide-and-conquer technique is the basis of efficient algorithms for many problems, such as sorting (e.g., quicksort, merge sort), multiplying large numbers (e.g., the Karatsuba algorithm), find...
Divide-and-Conquer Abstract The divide-and-conquer is an important technique for design of algorithms. In this chapter, we will employ several examples to introduce this technique, including the rectilinear minimum spanning tree, the Fibonacci search method, and the sorting problem. Sorting is not ...
Following are some standard algorithms that are Divide and Conquer algorithms. 1)Quicksortis a sorting algorithm. The algorithm picks a pivot element, rearranges the array elements in such a way that all elements smaller than the picked pivot element move to left side of pivot, and all greater...
