An implementation of maxflowmincost problem solution.
For references see:
- Edmonds-Karp max flow algorithm
- Dijkstra and Bellman-Ford shortest path algorithms
With this in mind here is an explanation of maxflowmincost:
Instead of finding the shortest path from source to sink in a sense of number of nodes (via BFS) we are using Dijkstra to find the "cheapest" path (the shortest in a cost sense) and then trying to push the flow along this path. That's all.
