Consider the following network which represents the relation between the different [ warehouses of a company where each node represents the warehouse and the edge M reflects the connection between them. Value in the edge reflects the maximum capacity that can be carried at a time. 12 16 20 9 10 13 14 Apply Ford-Fulkerson method to find the maximum flow from source npde s to sink node t from above network. Show each significant steps of your calculation. Note that warehouse 3 and 4 has storing capacity 2 and 4 respectively. Choose the path that has fewest edges while considering augmenting path.
