WebAll previously known efficient maximum-flow algorithms work by finding augmenting paths, either one path at a time (as in the original Ford and Fulkerson algorithm) or all shortest-length augmenting paths at once (using the layered network approach of Dinic). An alternative method based on the preflow concept of Karzanov is introduced. A ... WebThe overall structure of the algorithm is similar to Edmonds{Karp or Dinic. Blocking ows are found for level graphs of increasing depth. The better time bound is due to an O(n2 logn) (or O(n2) with Fibonacci heaps) method for producing a blocking ow. For this algorithm, we need to consider the capacity of a vertex as opposed to the capacity of ...
