WebJun 21, 2024 · The problem is to find a permutation of the tasks such that the time needed to execute all of them is minimized. My intuition says that this can be solved with a greedy algorithm, by scheduling the tasks in descending a i order. For example given the tasks with: m 1 = 3, a 1 = 9 m 2 = 2, a 2 = 7 m 3 = 6, a 3 = 10 WebYou’llprobably have 2 (or 3…or 6) ideas for greedy algorithms. Check some simple examples before you implement! Greedy algorithms rarely work. When they work AND …
