Editing Max-flow min-cut theorem (section)

===Cederbaum's maximum flow theorem===
{{See also| Cederbaum's maximum flow theorem}}
The maximum flow problem can be formulated as the maximization of the electrical current through a network composed of nonlinear resistive elements.<ref>{{cite journal|last1=Cederbaum|first1=I.|title=On the optimal operation of communication nets|journal=Journal of the Franklin Institute|date=August 1962|volume=274|issue=2 |pages=130–141|doi=10.1016/0016-0032(62)90401-5 }}</ref> In this formulation, the limit of the current {{math|&thinsp;''I''<sub>in</sub> }} between the input terminals of the electrical network as the input voltage {{math|''V''<sub>in</sub>}} approaches <math>\infty</math>, is equal to the weight of the minimum-weight cut set. 

:<math>\lim_{V_{\text{in}} \to \infty} (I_{in})= \min_{X_C}\sum_{(u,v) \in X_C}c_{uv} </math>
