How to find the maximum flow in a multi source flow network?
How to convert this multi source flow network in to single source flow network and find the maximum flow in that?
Solution
You create a dummy source node, called Source, and draw a directed edge of close-to-infinite-capacity (e.g. sum of capacities of all edges of the graph) from Source to each tank. Every flow in the resulting graph is in one-to-one correspondence with the original multi-source graph.
