### Set Cover Problem | Set 1 (Greedy Approximate Algorithm ...

Mar 22, 2017 · 2-Approximate Greedy Algorithm: Let U be the universe of elements, {S 1, S 2, …S m} be collection of subsets of U and Cost(S 1), C(S 2), …Cost(S m) be costs of subsets. 1) Let I represents set of elements included so far. Initialize I = {} 2) Do following while I is not same as U. a) Find the set S i in {S 1, S 2, ...S m} whose cost effectiveness is smallest, i.e., the ratio …

### Discrete Cosine Transform (Algorithm And Program ...

Jan 20, 2021 · Algorithm : Let we are having a 2-D variable named matrix of dimension 8 X 8 which contains image information and a 2-D variable named dct of same dimension which contain the information after applying discrete cosine transform. So, we have the formula dct[i][j] = ci * cj (sum(k=0 to m-1) sum(l=0 to n-1) matrix[k][l] * cos((2*k+1) *i*pi/2*m) * cos((2*l+1) *j*pi/2*n)

### DAA Quick Sort - Javatpoint

Quick sort. It is an algorithm of Divide & Conquer type. Divide: Rearrange the elements and split arrays into two sub-arrays and an element in between search that each element in left sub array is less than or equal to the average element and each element in the right sub- array is larger than the middle element. Conquer: Recursively, sort two sub arrays.

### Single-linkage Clustering - Wikipedia

The naive algorithm for single linkage clustering is essentially the same as Kruskal's algorithm for minimum spanning trees. However, in single linkage clustering, the order in which clusters are formed is important, while for minimum spanning trees what matters is the set of pairs of points that form distances chosen by the algorithm.

### Disjoint Set Union - Algorithms For Competitive Programming

Disjoint Set Union. This article discusses the data structure Disjoint Set Union or DSU.Often it is also called Union Find because of its two main operations.. This data structure provides the following capabilities. We are given several elements, each of which is a separate set.
