This can be used to overcome the traffic congestion problem, and we propose a method here. In Figure 7.19 we will arbitrarily select the path 1256. Maximum flow minimum cut is a famous problem in graph theory, which helps to fine the maximum flow possible in any given network. Nothing in between will change their capacity - so there is nothing to compute/calculate other than which end has the smaller total capacity.Excel is not needed for the solution. # ) I # P=i_k > it6-UAl3=_-.KKKA^U ;: C2h\ * 3 $ 36 > * W\__F3L_/VAF4 tI. • Maximum flow problems find a feasible flow through a single-source, single-sink flow network that is maximum. << 4JTm5FD/=2j[s[Rk5EA-?n9*-$6U)H_?

An example of this is the flow of oil through a pipeline with several junctions. It is defined as the maximum amount of flow that the network would allow to flow from source to sink.
