Question
Time complexity of Ford fulkerson Algorithm is
Solution
The time complexity of the Ford-Fulkerson algorithm is O(max_flow * E), where E is the number of edges in the graph and max_flow is the maximum flow in the graph.
Here's a step-by-step explanation:
-
The Ford-Fulkerson algorithm works by repeatedly augmenting the flow along a path from the source to the sink in the residual graph.
-
The time complexity for finding whether there is a path from source to sink is O(E), where E is the number of edges in the graph. This is because in the worst case, we may have to traverse all the edges of the graph.
-
The maximum number of times we can augment the flow (i.e., the maximum number of paths we can find) is equal to the maximum flow in the graph, which we denote as max_flow.
-
Therefore, the total time complexity of the algorithm is O(max_flow * E), because for each unit of flow that we push through the network, we could potentially have to traverse each edge once.

In the context of the maximum flow problem in a network graph, what does the Ford-Fulkerson algorithm typically use to find the maximum flow?Select one:a. It finds the longest path from the source to the sink and determines the flow based on this path.b. It calculates the minimum capacity of all edges in the network and uses that as the maximum flow.c. It divides the graph into equal halves and calculates the flow for each half separately.d. It uses augmenting paths to increase the flow until no more augmenting paths are found.
