• The activity selection problem is characteristic of this class of problems, where the goal is to pick the maximum number of activities that do not clash with each other. • In the Macintosh computer game Crystal Quest the objective is to collect crystals, in a fashion similar to the travelling salesman problem. The game has a demo mode, where the game uses a greedy algorithm to go to every crystal. The artificial intelligence does not account for obstacles, so the demo mode often ends q… immuni app windows 10WebJun 5, 2024 · 1 Answer. The algorithm has an approximation ratio of Δ + 1, where Δ is the maximum degree of the input graph G. That is, the resultant independent set, denoted as S, satisfies S ≥ 1 Δ + 1 O P T , where O P T is a maximum … immunic therapeutics aktieWebThe greedy algorithm produces a lnn-approximation algorithm for the Set Cover problem. What does it mean to be a lnn-approximation algorithm for Set Cover? The goal of Set Cover seeks to minimize the sum of set weights, or just the number of sets chosen because we assume w j = 1.
