Question 1.
What is the main purpose of the Floyd-Warshall algorithm?
Show hintHide hint
Think about where this might be applied in real-world scenarios.
Question 2.
What does the term 'negative edge weights' refer to?
Show hintHide hint
Consider how these might affect connectivity.
3Question 3.
What is the primary function of the Floyd-Warshall algorithm?
- To find the shortest path from a single source
- To find shortest paths between all pairs of vertices
- To detect negative cycles
Show hintHide hint
Think about its operation on every vertex.
4Question 4.
Floyd-Warshall allows negative edge weights but not negative cycles. True or False?
- True
- False
Show hintHide hint
Recall the conditions necessary for the algorithm to function correctly.
Question 5.
Given a directed graph with the following edges and weights, compute the shortest paths using the Floyd-Warshall algorithm. Edge List: (1,2,10), (1,3,5), (2,3,2), (3,1,5).
Show hintHide hint
Start with initializing a matrix with edge weights and apply the induction process for all vertices.
Question 6.
Consider the practical applications of the Floyd-Warshall algorithm in AI for pathfinding. How would this algorithm perform in misleading terrain with false path weights?
Show hintHide hint
Think about conditions that lead to incorrect computations in pathfinding.
