Challenge Problems

Push your limits with challenges.

Question 1

Create a weighted graph with at least 5 vertices containing both negative and positive weights. Apply the Floyd-Warshall algorithm to find the shortest paths and discuss the results.

💡 Hint: Make sure to include the edges and their weights clearly.

Question 2

Analyze a scenario where the Floyd-Warshall fails due to a negative cycle present in the graph. Explain the consequences.

💡 Hint: Reflect on what a negative cycle does to pathweight over cycles.
