Question
The maximal flow solution algorithm allows the user to choose a path through the network from the origin to the destination by any criteria.
Solution
Yes, the maximal flow solution algorithm, also known as the Ford-Fulkerson method, allows the user to choose any path from the source (origin) to the sink (destination) in a network. The algorithm works by repeatedly augmenting the flow along these paths. Here are the steps:
-
Start with an initial flow, which could be zero flow for all edges in the network.
-
Find an augmenting path from the source to the sink in the residual graph. The residual graph is a graph which indicates additional possible flow. If no such path exists, go to step 4.
-
Augment the flow along this path. This means to increase the flow on that path by the amount of the smallest capacity on the path. Update the residual graph to reflect this change.
-
If no augmenting paths are left, the current flow is maximal. The algorithm terminates.
The choice of the augmenting path can be done by any criteria, as long as it is a valid path from the source to the sink in the residual graph. The algorithm does not specify a particular method for choosing the path.

The diagram below shows an input network for the minimum-cost flow problem, and the flow (shown in red) in this network at the end of the 2-nd iteration of the Successive Shortest Path algorithm. During the computation, whenever there is a choice of a vertex, the algorithm selects the vertex which is first in the lexicographical order. (This means, for example, that during the first iteration, the algorithm selected vertex p1 from the two available supply vertices, and selected vertex r1 from the two available demand vertices.)
