Question: Let G = ( V , E ) be a directed graph with source s in V , sink t in V and nonnegative edge

Let G =(V, E) be a directed graph with source s in V , sink t in V and nonnegative edge capacities {ce}. Give a polynomial time algorithm to decide whether G has a unique minimum s t cut (i.e., an s t cut of capacity strictly less than that of all other s t cuts.)
