[1] Any cut determines a cut-set, the set of edges that have one endpoint in each subset of the partition. These edges are said to cross the cut. In a connected graph, each cut-set determines a unique cut, and in some cases cuts are ...

WebGraph theory is very useful in design and analysis of electronic circuits. It is very useful in designing various control systems. E.g. Signal Flow Graphs and Meson's Rule make your life a lot easier while trying to find transfer functions. Also, while solving differential equations numerically Graph Theory is used for mesh generation. WebOct 27, 2016 · 2. The "capacity" of a cut is used as an upper bound on the flow from the source to the sink. The "capacity" of the cut is therefore equal to maximal flow that can cross the cut from the source to the sink. For this graph, that is at most 26. If you would subtract the backward edges, you no longer have an upper bound (you could even end …
