The objectives are

- List properties of graphs including incident, adjacent, neighbors, degree, isolated, and pendant
- Identify in-degree and out-degree on directed graphs
- Represent graphs with adjacency matrixes
- Represent graphs with adjacency lists
- Finds paths, simple paths, and circuits in graphs
- Determine is a graph is connected
- Find strongly connected components in a graph
- Apply Dijkstra's shortest path algorithm to graphs
- Learn Floyd's all-pairs shortest path algorithm

- (6 points) 10.6.8 - Extend Dijkstra's algorithm to compute the actual path as well as the mileage. Show your work. Report both the mileage and the path.
- (6 points) 10.6.21 - Extend Floyd's algorithm to compute the actual path as well as the cost. Report the cost between
*a*and*z*and show how the path is reconstructed from your extension. - (
**6 points Extra Credit**) Draw the “call graph” of the following program fragment. (The nodes of a call graph are methods and the edges are method calls)- What do cycles in a call graph mean?
- What does it mean if the graph is disconnected?
