Imagine you are the logistics manager of a company. You need to create a cost-effective route to deliver items to five locations using Dijkstra’s algorithm. Draw the graph and calculate the shortest path.
💡 Hint: Start at one of the locations and continually update the cost to reach other locations.
Given a weighted graph with negative edge weights, demonstrate how the Bellman-Ford algorithm functions and computes shortest paths. Include a visual representation.
💡 Hint: Remember, this algorithm involves systematically relaxing edges multiple times.
