WebJul 17, 2024 · When faced with a new difficult problem, it's not hard to come up with a greedy solution using the four steps described in the previous section. All you have to do is divide your problems into phases and determine which greedy rule to apply at each step. That is, you do the following: Web(c) The denominations f1;17;30gand n = 34 is one of the many examples where greedy algorithm gives a sub-optimal solution. Greedy solution is four 1’s and one 30 for a total of ve coins whereas optimal solution is two 17’s. Problem 2 In this problem we consider the following algorithm. Let x be the class with the earliest start time,

WebIt can be used to solve problems such as scheduling, Huffman coding, and finding the shortest path in a graph. Overall, the Greedy algorithm is a useful approach for solving optimization problems, but it should be used with caution, as it may not always lead to the best global solution.
