Consider the following network example. With the indicated link costs along each link in the figure, use Dijkstra's shortest-path algorithm to compute the shortest path from x to all network nodes. Show how the algorithm works by computing a table.
Answer: Let N' denote the set of nodes whose distance have been known so far, D(s) be the distance to a node s, and p(s) be the parent node of the node s on the shortest path from s to node x. We then construct the following table.
