Question: Answer the following questions on the flow network N and flow f shown in Figure 16.6a: What are the forward and backward edges of augmenting

Answer the following questions on the flow network N and flow f shown in Figure 16.6a: 

  • What are the forward and backward edges of augmenting path π? 
  • How many augmenting paths are there with respect to flow f? For each such path, list the sequence of vertices of the path and the residual capacity of the path. 
  • What is the value of a maximum flow in N?
