3 cards from this section. Quick, good the night before a test.
What is the first step in initializing the Bellman-Ford Algorithm?
Think about how you would create a baseline for distance values.
What does 'relaxation' mean in the context of shortest paths?
Consider the process of finding a better way to get somewhere.
What is the maximum number of iterations required for the Bellman-Ford Algorithm?
Think about how many edges we can have in the longest path in a graph.
True or False: The Bellman-Ford Algorithm can handle graphs with negative cycles.
Consider the implications of having a cycle that lowers path cost repeatedly.
Create a graph with 5 vertices including at least 2 negative edges. Apply the Bellman-Ford Algorithm and track the distance updates over each iteration.
Make sure to visualize the graph and update distance values as you go through iterations.
In what scenario would the Bellman-Ford Algorithm be more advantageous than Dijkstra's Algorithm? Provide a specific example.
Think about the types of real-world problems where costs can decrease.
