WebThe WeightMap has to map each edge from E to nonnegative number, and each edge from ET to -weight of its reversed edge. The algorithm is described in Network Flows . This algorithm starts with empty flow and in each round augments the shortest path (in terms of weight) in the residual graph. In order to find the cost of the result flow use ...
