Q5. Trace the execution of Dijkstra's algorithm for the following graph. You need to show each step and values of Extract-Min(Q), values of v.d, and V.I for each node as the algorithm progresses. Draw the final shortest path tree.

Step 1
Start at node A. Set A.d = 0 and all other nodes' d values to infinity. Set all nodes' V.I values to false except for A, which is true. Show more…

You are given the above unweighted graph and want to find the shortest path from node A to node P using A* Search. Your algorithm has the following properties: - It uses Manhattan distance as its heuristic (the h-value). - If two nodes look equally good, it breaks ties by selecting the node with a smaller heuristic (or, equivalently, the node with the largest distance traveled). - If two nodes are still tied, it breaks ties by choosing the node which comes first alphabetically. For each of the nodes, specify the g-value and h-value when they are discovered. Then, specify the order in which nodes are explored, stopping once P is explored.

Suppose we run Dijkstra's algorithm from a start node s in a weighted undirected graph. The distance to each reachable node t is given by distTo.get(t). What do we know about the shortest path between any two other nodes u and v—assuming neither is the start node? Explain your reasoning for all 4 answer choices. (It is sufficient to give a counterexample for incorrect answers.) There can only exist a single shortest path from u to v. A shortest path from u to v must include one or more edges in the shortest paths tree from s. If the shortest paths tree reaches u and v, then u and v are connected. The distance of a shortest path from u to v cannot be greater than distTo.get(u) + distTo.get(v).
