While there is an augmenting path between the source and the sink, add this path to the flow. Update the residual graph. We can also consider reverse-path if required because if we do not consider them, we may never find a maximum flow. free fortnite cheats dll

Network Flow and the Maximum Flow Problem

WebSink flow is literally opposite to the source flow. In sink flow, fluid moves radially inward (or absorbs fluid) towards a point known as sink, and fluid disappear at sink at a constant rate. Fig.b shows a sink flow, the point O is known as sink. The equation of radial velocity in sink flow is similar but with a sign change to q. WebMin-Cut Max-Flow Theorem.
