Determining of a maximal network flow is a classic problem in discrete optimization with many applications. In this paper, a new algorithm based on the Dinic's method is presented. Algorithms of the Dinic's method work evidently faster than theoretical bounds for a randomized network. This paper...
Here is a possible solution of the problem with some help of [min cost max flow algorithm: http://web.mit.edu/~ecprice/acm/acm08/MinCostMaxFlow.java https://en.wikipedia.org/wiki/Minimum-cost_flow_problem. The basic idea is to translate consumer id, group id to vertex of graph, tra...

Our improvement is reached by a novel combination of Ahuja and Orlin's excess scaling method and Orlin's compact flow networks. To our knowledge, this is the first $O(mn)$ time max-flow algorithm that runs on this range of networks. Further, we extend the range of Orlin's $O(mn)$ ...

The max-flow/min-cut theorem of Ford and Fulkerson has recently been extended to this wireless relay model. This result was first proved by a random coding scheme over large blocks of transmitted signals. We demonstrate the same result with a deterministic, polynomial-time algorithm which takes ...
