This is an alternate formulation to the Max Flow Problem.

- We want to remove some edges from the graph such that after removing the edges, there is no path from s to t.
- The cost of removing e is equal to c(e).
- The minimum cut problem is to find a cut with minimum total cost.

**Theorem**: Minimum Cut = Max Flow

Since we know the max flow, we can use the Residual Graph to find the min cut.

## Algorithm Edit

Steps:

- Mark all nodes reachable from S. Call this set of reachable nodes A.
- Now separate these nodes from the others. Cut edges going from A to V - A
- Now look at the original graph and find the cut.
