Question
Which of the following search algorithms require a priority queue to store the frontier set? Select two algorithms.Group of answer choicesDepth-First SearchA* SearchGreedy Best-First SearchGraph SearchBreadth-First SearchDepth-First Depth-Limited SearchTree SearchIterative Deepening
Solution
The two search algorithms that require a priority queue to store the frontier set are:
- A* Search
- Greedy Best-First Search
These algorithms use a priority queue to determine the next node to explore based on some priority, such as the shortest path in A* Search, or the most promising node in Greedy Best-First Search.
