Challenge Problems
Push your limits with advanced challenges
Consider a graph with vertices A, B, C, and D where A connects to B with weight 1, B to C with weight -2, and C to D with weight 2. How do the distances from A to all vertices evolve through the Bellman-Ford algorithm?
💡 Hint: Iterate through all edges and update distances accordingly.
Design a strange graph where negative cycles appear yet ensure Bellman-Ford can’t find them. What is their impact on path calculations?
💡 Hint: Use examples of loops to draw a clear distinction.
