Problem 2: Dijkstra part 2 a) Use Dijkstra's

Problem 2: Dijkstra part 2 a) Use Dijkstra's algorithm to find the shortest path (distances and which nodes to take) from node 4 to every other node. Complete the full algorithm (from initialization to the final paths and distances). 12 2 6 5 1 3 2 4 15 1 4 12 3 8 5 3 4 Problem 4: Consider the network given in problem 2. Let N represent the set of nodes and A represent the set of arcs. The net difference of each node is presented in the following table: Nodej 1 2 3 4 5 6 Net difference, b; 110 -50 0 20 -60 -20 a) Formulate this as a minimum cost flow problem. Write out in non-set notation. Note: rather than costs, Cij, refer to distance, dij as provided in the network diagram. = b) Now consider bs flow problem. -80. Redraw the network and reformulate as a new minimum cost
