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 approach for solving a problem by selecting the best option available at the moment.
