Short answer
If the state of the visited, tentativeDistance, and predecessor arrays used in Dijkstra's algorithm are as shown below, what vertex was used as the start node? (Your answer should be an integer node index) Note: the string "inf" represents the value "positive infinity".

To identify the start node in Dijkstra’s run, we look for the vertex whose tentative distance is 0, since the algorithm initializes the start vertex with distance 0 and all others with infinity (or a large value).

Dijkstra’s Link-State Algorithm Consider the following network. With the indicated link costs, use Dijkstra’s shortest-path algorithm to compute the shortest path from x to all network nodes. Show how the algorithm works by computing the distance from x to all network nodes. Notes : When the distance is infinity, write in the abbreviation "inf". When there is a tie in node distances, please choose from left to right, i.e. the node in the left column is chosen first. For the N* node-set, for example, if the node-set contains nodes, x, y, and z, enter xyz in the blanks. For the D(.),p(.) column, enter in the format of "Distance, Predecessor", for example, 5,u in the blanks. Compute the distance from x to all network nodes.

If Dijkstra's algorithm is performed on the graph with vertex set { 0 , 1 , 2 , 3 , 4 , 5 } and adjacency matrix given below, what is the sequence of edges added to the result (shortest path tree). Use vertex 0 as a source. We break ties between vertices by picking the vertex with lower index. For example, EXTRACT-MIN returns vertex 1 before vertex 2, if both vertices have the same minimum estimate. ( 0 8 5 9 6 3 8 0 2 2 5 2 5 2 0 3 1 7 9 2 3 0 1 9 6 5 1 1 0 9 3 2 7 9 9 0 )
