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 WebNov 10, 2024 · Additionally, the greedy selection of actions, although maybe not the best approach to solving the bandit problem, is often used to choose between different actions in RL. The second main area of use for bandit algorithms is during real world testing. This can be in any field but is particularly prevalent in online commerce, healthcare and finance.
