WebOct 11, 2024 · There are many applications of greedy algorithms and we walked through two examples in this article — the fractional knapsack problem and the coin change problem. In cases where the greedy algorithm fails, i.e. a locally optimal solution does not lead to a globally optimal solution, a better approach may be dynamic programming (up … WebMar 10, 2006 · then using the greedy algorithm to finish up the rest [1]. In particular, consider all O(knk) possible subsets of objects that have up to k objects, where k is some fixed constant [1]. Then for each subset, use the greedy algorithm to fill up the rest of the knapsack in O(n) time. Pick the most profitable subset A.
