Use the Ford-Fulkerson's algorithm to find the maximum flow from s to t, where the numbers on the arcs represent the capacities. A 6 4 3 G 2 D 2 1 3 (В 6 2 E 2 3 ... WebFord-Fulkerson Algorithm 1) Start with initial flow as 0. 2) While there is a augmenting path from source to sink. Add this path-flow to flow. 3) Return flow. Time Complexity: Time complexity of the above algorithm is O(max flow * E) We run a loop while there is an augmenting path. In worst case, we may add I unit flow in every iteration.
