"Web13 apr. 2024 · The max-flow min-cut theorem states that flow must be preserved in a network. So, the following equality always holds: f (u, v) = -f (v, u). f (u,v) = −f (v,u). With these tools, it is possible to calculate the residual capacity of any edge, forward or backward, in the flow network. " - Max flow network
