When would best first search be worse than breadth first search?

• 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… WebOct 11, 2024 · Let’s discuss some of the informed search strategies. 1. Greedy best-first search algorithm. Greedy best-first search uses the properties of both depth-first search and breadth-first search. Greedy best-first search traverses the node by selecting the path which appears best at the moment. The closest path is selected by using the heuristic ... WebNov 15, 2024 · 3. In general case best first search algorithm is complete as in worst case scenario it will search the whole space (worst option). Now, it should be also optimal - given the heuristic function is admissible - meaning it does not overestimate the cost of the path from any of the nodes to goal. phosphonate formula
