Question 1.
What is the primary purpose of the Bellman-Ford algorithm?
Show hintHide hint
Consider the situations where Dijkstra's algorithm fails.
Question 2.
Define negative cycles in the context of graphs.
Show hintHide hint
Think of paths that can reduce distance continuously.
3Question 3.
What is the main restriction of the Bellman-Ford algorithm?
- Allows negative cycles
- Requires positive edges only
- Allows negative edges but not cycles
- None of the above
Show hintHide hint
Review the importance of negative cycles in graphs.
4Question 4.
True or False? The Dijkstra's algorithm can be applied to graphs with negative weights.
- True
- False
Show hintHide hint
Think about the assumptions each algorithm makes.
Question 5.
Given a graph with vertices and edges including both negative and positive weights, illustrate the processes of the Bellman-Ford algorithm showing each iteration's distance updates until stabilization.
Show hintHide hint
Be methodical and label each vertex clearly to track distances.
Question 6.
Consider a graph that includes a negative cycle. Describe how Bellman-Ford would behave and the ultimate impact this has on finding the shortest paths.
Show hintHide hint
Reflect on the definition of shortest paths in relation to negative cycles.
