Challenge Problems

Push your limits with challenges.

Question 1

Given a directed graph with the following edges and weights, compute the shortest paths using the Floyd-Warshall algorithm. Edge List: (1,2,10), (1,3,5), (2,3,2), (3,1,5).

💡 Hint: Start with initializing a matrix with edge weights and apply the induction process for all vertices.

Question 2

Consider the practical applications of the Floyd-Warshall algorithm in AI for pathfinding. How would this algorithm perform in misleading terrain with false path weights?

💡 Hint: Think about conditions that lead to incorrect computations in pathfinding.
