Cоnsider the netwоrk in the figure belоw. The link costs аre lаbeled on the edges. (а) (2 points) What is the distance vector for each node after the distance vector algorithm converges. You can answer the question using a table like below, where the rows are distance vectors. w x y z w x y z (b) (2 points) Verify the Bellman-Ford equation for the cost for the least-cost path from node w to x. Use notations such as d(w, x) for the least path cost from node w to node x, and c(w, y) for the link cost for the link (w, y). (c) (2 points) Suppose poisoned reverse is used. Write out the information that node y keeps locally using a similar table. Recall that a node keeps its own distance vector and the neighbors’ distance vectors. (d) (3 points) Now suppose the link cost between x and y increases to 60. Will there be a bad-news-travel-slowly problem even if poisoned reverse is used? Why or why not? Justify your answer. (e) (3 points) How many iterations are needed for the distance-vector algorithm to converge? Justify your answer. Hint: For (d) and (e), consider the path costs to reach node x. You can justify your answer by considering the iterations. You can either describe the iterations in words or fill a table like below. You don’t have to fill in entries for all the iterations, but only need to find a pattern by considering several iterations. Use the notation D(y,x) for the path cost from node y to node x during each step of the algorithm. Also note that, in each iteration, only the nodes with changed costs will advertise to the neighbors. For the advertisement, you can use the notations such as ‘u->v: D(u,x)=10’ to mean node u advertises cost D(u,x)=10 to node v; and ‘u->s: D(u,x)=inf’ to mean node u advertises cost D(u,x)=infinity to node s. Iterations Path cost to x Which nodes have new costs Advertised costs to neighbors 0 (before the change of the link cost) D(y,x)= D(w,x)= D(z,x)= N/A N/A 1 D(y,x)= D(w,x)= D(z,x)= 2 D(y,x)= D(w,x)= D(z,x)=
Jаmes оwns а restаurant in Bооne, Iowa, and he employs 20 people. He hires waiters and waitresses to serve his customers He hires Leslie, a 25 year old shy woman with waitressing experience. James pays her $8/hour plus tips. Leslie does not have an employment contract. After working for two weeks, James fires Leslie because he does not think she is working out at the restaurant. He tells her, "You are too quiet! You don't smile enough. I need my waitresses and waiters to be chatty with the customers." He hires an outgoing male to take her place. Leslie thinks this is unfair and discriminatory. She wants to sue, and she asks you to advise her. What do you tell her?
