Challenge Problems
Push your limits with challenges.
Question 1
Consider a graph with vertices A, B, C, and D connected by edges with the following weights: A-B: 4, A-C: 2, C-B: 5, B-D: 1. Calculate the shortest path from A to D using Dijkstra's algorithm.
💡 Hint: Keep track of the lowest costs as you move through unvisited vertices.
Question 2
You have a weighted graph where some edges are negative. What will happen when applying Dijkstra's Algorithm, and what alternative would you consider?
💡 Hint: Review the properties of the algorithms for different contexts.
