• 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… WebHi, in this video we'll talk about greedy or nearest neighbor matching.
