2 cards from this section. Quick, good the night before a test.
What is a weighted graph?
Think about graphs with costs like distances.
Name one application of weighted graphs.
Think about systems where some paths may cost more than others.
What characterizes a weighted graph?
Focus on what the edges imply in terms of graph representation.
True or False: Dijkstra's algorithm can be used effectively on unweighted graphs.
Think about how edge weights affect the algorithm.
Given a weighted graph with vertices representing cities and edges as roads with costs, outline how you would employ Dijkstra’s algorithm to find the least expensive route from City A to City C.
Visualize the graph and track costs methodically.
Create a unique scenario with a weighted graph where Dijkstra’s algorithm may produce different outcomes when edge weights are modified.
Think about real-life implications, like changing speed limits affecting travel time.
