How accurate is greedy algorithm

Web16 de abr. de 2024 · Greedy algorithms tend to be very efficient and can be implemented in a relatively straightforward fashion. Many a times in O(n) complexity as there would be a single choice at every point. However, most attempts at creating a correct greedy algorithm fail unless a precise proof of the algorithm's correctness is first demonstrated. WebA greedy algorithm, on the other hand, is what you described: an algorithm that tries to find the best solution by selecting the best option at every step. That's pretty much it. …
