WebTheorem A Greedy-Activity-Selector solves the activity-selection problem. Proof The proof is by induction on n. For the base case, let n =1. The statement trivially holds. For the induction step, let n 2, and assume that the claim holds for all values of n less than the current one. We may assume that the activities are already sorted according to WebA greedy algorithm is an algorithm which exploits such a structure, ignoring other possible choices. Greedy algorithms can be seen as a re nement of dynamic programming; in … WebIn order to determine which activity should use which lecture hall, the algorithm uses the GREEDY-ACTIVITY-SELECTOR to calculate the activities in the first lecture hall. If there are some activities yet to be scheduled, a new lecture hall is selected and GREEDY-ACTIVITY-SELECTOR is called again. This continues until all activities have been ... chubby name
