5 cards from this section. Quick, good the night before a test.
What data structure does BFS utilize to explore nodes?
Think about the principle of serving at a cafeteria.
Is BFS a complete search strategy?
Recall that completeness means finding a solution if one exists.
What does BFS stand for?
Think about its method of exploration.
Is BFS optimal if all costs are not the same?
What happens when costs vary?
Given a branching factor of 4 and a depth of 5 for a BFS, calculate the maximum number of nodes that can be explored.
Use the formula for nodes in a tree structure.
If a path requires traversing 10 nodes with varying costs: 1, 1, 2, 1, 5, 1, 0, 2, 4, 3, discuss whether BFS is optimal in this scenario.
Think about the role of cost in determining the best path.
