(and one on Amortized Analysis) Name:1. Consider the following undirected, weighted graph:
Step through Dijkstra's algorithm to calculate the single-source shortest paths from A to every other
vertex. Show your steps in the table below. Cross out old values and write in new ones, from left toright within each cell, as the algorithm proceeds. Also list the vertices in the order which you marked
them known. Finally, indicate the lowest-cast path from node A to node F.Solution:

FY6D GY8F (b) Dijkstra's algorithm found the wrong path to some of the vertices. For just the vertices where the wrong path was computed, indicateboththe path that was computed and the correct path. (c) Whatsingleedge could be removed from the graph such that Dijkstra's algorithm would happen to compute correct answers for all vertices in the remaining graph?Solution:
(b) Computed path to G is A,B,D,F,G but shortest path is A,C,E,G. Computed path to D is A,B,D but shortest path is A,C,E,G,D. Computed path to F is A,B,D,F but shortest path is A,C,E,G,D,F. (c) The edge from E to G. Name:3. Suppose we dene a dierent kind of graph where we have weights on the vertices and not the edges.
Does theshortest-paths problemmake sense for this kind of graph? If so, give a precise and formaldescription of theproblem. If not, explain why not. Note we are not asking for an algorithm, just what
the problem is or that it makes no sense.Solution:
Yes, this problem makes sense: Given a starting vertexvnd the lowest-cost path fromvto every other vertex. The cost of a path is the sum of the weights of the vertices on the path. Name:4. Consider using a simple linked list as a dictionary. Assume the client will never provide duplicate
elements, so we can just insert elements at the beginning of the list. Now assume the peculiar situation
that the client may perform any number of insert operations but will only ever perform at most one lookup operation. (a) What is the worst-case running-time of the operations performed on this data structure under the assumptions above? Brie y justify your answer. (b) What is the worst-case amortized running-time of the operations performed on this data structure under the assumptions above? Brie y justify your answer.Solution:
(a) inserts areO(1) (push on the front of a linked list), but the lookup isO(n) wherenis the number of inserted items since the lookup may be last and be for one of the earliest inserted items (b) amortized all operations are nowO(1). Inserts are stillO(1). And the lookup can take at most timeO(n) wherenis the number of previously inserted items. So the total cost of anynoperations is at mostO(n), which is amortizedO(1).quotesdbs_dbs19.pdfusesText_25[PDF] dine in restaurants near me open
