Here, we will learn to use greedy algorithm for a knapsack problem with the example of Robbery using Python program. Submitted by Anuj Singh, on May 12, 2020 Unfortunately, a thief targeted a house and there he found lots of items to steal. Now each item has its value (quantified)...
public static int knapSack (int W, int n, int [] wt, int[] v) { int [][] dp = new int [n+1][W+1]; for (int i = 0; i < n+1; i++) { for (int j = 0; j < W+1; j++) { if (i == 0) dp[i][j] = wt[i] <= j? v[i] : 0; else { if...

1. Greedy Choice Property If an optimal solution to the problem can be found by choosing the best choice at each step without reconsidering the previous steps once chosen, the problem can be solved using a greedy approach. This property is called greedy choice property. ...
Some common examples of problems that can be solved using Greedy algorithms include the Activity Selection Problem, Knapsack problem, the Minimum Spanning Tree problem, and the Huffman coding problem. We can take an example ofActivity Selection Problemto understand the greedy approach. This problem is...
Although these modifications have significantly enhanced IBBA’s performance in feature selection tasks, their applicability to other problem domains—such as the traveling salesman problem, knapsack problem, and global optimization problems—remains to be explored. 2. In this study, when handling high...
