I understand the Ford-Fulkerson's method for finding the max flow, but I'm having trouble understanding how min-cut gives the value of max flow.... MODELING NETWORK FLOW BY EXCEL SOLVER G. Panayotova, Sl. Slavova State University of Library Studies and Information Technology, Sofia, Bulgaria ABSTRACT This paper presents two modeling approaches for solving the max flow problem and Min-Cut Problems. We have illustrated it using a numerical example and formulated two spreadsheets models using the popular spreadsheet …

Maximum Flow Theorem A ﬂow has maximum value if and only if it has no augmenting path. Proof: Flow is maximum ⇒ No augmenting path (The only-if part is easy to prove.) No augmenting path ⇒ Flow is maximum (Proving the if part is more difﬁcult.) Maximum Flow 9 Ford & Fulkerson Algorithm • One day, Ford phoned his buddy Fulkerson and said, “Hey Fulk! Let’s formulate an algorithm to... • Max-ﬂow min-cut theorem is a special case of linear programming duality.

## How To Find Max Flow Min Cut

• Max-ﬂow min-cut theorem is a special case of linear programming duality. Total unimodularity • A matrix A is totally unimodular if each subdeterminant of A is 0,+1 or − 1.

- Use the max-flow min-cut theorem, i.e., the capacity of a minimum capacity cut is equal to the flow value of a maximum flow. Parameters: G ( NetworkX graph ) – Edges of the graph are expected to have an attribute called ‘capacity’.
- Max Flow Min Cut Algorithm jacques@ucsd.edu Example 1. Find a maximum st-flow and st-minimum cut in the network below starting with a flow of zero in every arc.
- Use the max-flow min-cut theorem, i.e., the capacity of a minimum capacity cut is equal to the flow value of a maximum flow. Parameters: G ( NetworkX graph ) – Edges of the graph are expected to have an attribute called ‘capacity’.
- When this maplet is run, it allows the student to examine the Max Flow - Min Cut Theorem. Students can compare the value of the maximum flow to the value of the minimum cut, and determine the edges of the minimum cut as well as the saturated edges. Students can observe the graph with the minimum cut
