Question 1.
What is a weighted graph?
Show hintHide hint
Think about what makes them different from unweighted graphs.
Question 2.
Define the weight function.
Show hintHide hint
What does it help us determine in the graph?
3Question 3.
What does Dijkstra's Algorithm primarily find?
- Shortest path from a source vertex
- Longest path from a source vertex
- All paths in the graph
Show hintHide hint
Recall the main purpose of Dijkstra's Algorithm.
4Question 4.
True or False: Dijkstra's algorithm can be used for graphs with negative edge weights.
- True
- False
Show hintHide hint
Consider how the algorithm evaluates edge weights.
Question 5.
Your city has a new public transit system represented as a weighted graph. Analyze how Dijkstra's algorithm would determine the quickest route for a commuter.
Show hintHide hint
Visualize the graph and calculate edge weights carefully.
Question 6.
Propose an optimization to Dijkstra's algorithm that could enhance performance in large graphs.
Show hintHide hint
Think about data structures and their impact on time complexity.
