Let f be a maximum flow in G. Find an algorithm that determines whether there exists a unique min-cut in G. I have managed to find a similar question on this site: Determining the uniqueness of a min-cut. A summary of the answer given there: Find all the vertices reachable from s in the residual graph and we've found a min-cut (S,T) in G.

Unique mincut. Given an s-t flow network, determine whether the mincut is unique. Hint: solve s-t mincut problem in G and in G^R. Unmatchable edges in a bipartite graph. Given a bipartite graph G, an edge is unmatchable if it does not appear in any perfect matching of G. Hint: if G has no perfect matching, then all edges are unmatchable ...

The idea is to use residual graph. Following are steps to print all edges of the minimum cut. 1) Run Ford-Fulkerson algorithm and consider the final residual graph. 2) Find the set of vertices that are reachable from the source in the residual graph. 3) All edges which are from a reachable vertex to non-reachable vertex are minimum cut edges.

Given a network G(V;E;s;t), give a polynomial time algorithm to deter-mine whether G has a unique minimum s-t cut. Solution: First compute a minimum s-t cut C, and define its volume by |C|. Let e1;e2;:::;ek be the edges in C. For each ei, try increasing the capacity of ei by 1 and compute a minimum cut in the new graph. Let the new minimum cut ...

The input graph may have parallel edges. For example consider the following example, the smallest cut has 2 edges. A Simple Solution use Max-Flow based s-t cut algorithm to find minimum cut. Consider every pair of vertices as source ‘s’ and sink ‘t’, and call minimum s-t cut algorithm to find the s-t cut. Return minimum of all s-t cuts.

Min-cut. Min-Cut of a weighted graph is defined as the minimum sum of weights of (at least one)edges that when removed from the graph divides the graph into two groups. Mechthild Stoer and Frank Wagner proposed an algorithm in 1995 to find minimum cut in an undirected weighted graphs. The algorithm works on a method of shrinking the graph by ...

The minimum cut (in red) has capacity 3. Increasing the capacity of each edge increases that cut to 6. So the connection from S to A becomes the new minimum cut with a capacity of 5. When all the edges have the same capacity, increasing the capacity of every edge by 1 will not change the minimum cut.

The supplementary question in the details is clearly false. The uniqueness of the maximum flow (in any of the possible interpretations of that term) does not imply the uniqueness of the minimum cut. Consider a flow network that consists of a singl...

Algorithm: Check if max flow is unique. Let N = (V,E,c,s,t) be a flow network such that (V,E) is acyclic, and let m = |E|. Describe a polynomial- time algorithm that checks whether N has a unique maximum flow, by solving ≤ m + 1 max-flow problems. Explain correctness and running time of the algorithm. run FF (Ford Fulkerson) once and save the ...

Without terminal nodes. The minimum cut problem in undirected, weighted graphs limited to non-negative weights can be solved in polynomial time by the Stoer-Wagner algorithm.In the special case when the graph is unweighted, Karger's algorithm provides an efficient randomized method for finding the cut. In this case, the minimum cut equals the edge connectivity of the graph.
