Question
Consider the flow network G shown in figure 1 with source s and sink t. The edge capacities are
the numbers given near each edge.
(a) Find a maximum flow in this network. Once you have done this, draw a copy of the original
network G and clearly indicate the flow on each edge of G in your maximum flow.
(b) Find a minimum s-t cut in the network, i.e. name the two (non-empty) sets of vertices that
define a minimum cut. Also, say what its capacity is.
