Greedy algorithm activity selection
WebA greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. ... The activity selection problem is β¦ Webtheory supporting greedy algorithms. 4.1 Greedy Algorithms A problem that the greedy algorithm works for computing optimal solutions often has the self-reducibility and a simple exchange property. Let us use two examples to explain this point. Example 4.1.1 (Activity Selection) Consider n activities with starting times
