Maximum flow problem example pdf
WebCuts Constrain Flows This theorem: Theorem Let f be any s-t ow and (A;B) be any s-t cut. Then v(f ) capacity(A;B). Says that any cut is bigger than any ow. Therefore, cuts constrain ows. The minimum capacity cut constrains the maximum ow the most. In fact, the capacity of the minimum cut always equals the maximum ow value. Web(For example, the max-flow for the 2-commodity flow problem in Figure 2 is one.) This commonly- used definition provides for a “fairness” property that ensures that proportionally more of one commodity will not be routed at the expense of another.
