WebJan 5, 2024 · One of the most popular greedy algorithms is Dijkstra's algorithm that finds the path with the minimum cost from one vertex to the others in a graph. This algorithm finds such a path by always going to the nearest vertex. That's why we say it is a greedy algorithm. This is pseudocode for the algorithm.

WebFeb 14, 2024 · The Greedy algorithm is characterized as complete, as it always returns a solution if exists. However, this algorithm does not guarantee the optimum solution. … Solution: 1. Create an empty solution-set = { }. Available coins are {5, 2, 1}. 2. We are supposed to find the sum = 18. Let's start with sum = 0. 3. Always select the coin with the largest value (i.e. 5) until the sum > 18. (When we select the largest value at each step, we hope to reach the destination faster.
