WebJun 24, 2016 · Input: A set U of integers, an integer k. Output: A set X ⊆ U of size k whose sum is as large as possible. There's a natural greedy algorithm for this problem: Set X := ∅. For i := 1, 2, …, k : Let x i be the largest number in U that hasn't been picked yet (i.e., the i th largest number in U ). Add x i to X. WebA greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not …

WebMay 17, 2011 · The minimum coin change problem is an NP-complete problem but for certain sets of coins the greedy algorithm (choose largest denominations first) works. Given a set of integers denoting coin-values, what's the fastest algorithm to determine if the greedy algorithm suffices or not? One obvious way is to build up your dynamic … WebAssume the greedy algorithm does not produce the optimal solution, so the greedy and optimal solutions are different.
