Network Flow Question
Which of the following alternatives contains a false statement regarding network flow? a) The residual network is obtained by subtracting the flow’s edge weights from their corresponding edges in the original network. b) Residual networks obtained from maximum flows have no augmenting path. c) To push flow into an edge, the original vertex needs to have excess flow and the same height as the destination vertex. d) The sum of the weights of all edges of a single vertex in a flow is always zero, except for the source and the sink. e) None of the above.
