Graph cut property

WebAug 14, 2014 · 2)A tree satisfies a cut property if and only if for each pair of nodes (u, v) the minimum cut in this tree is the same as in the original graph (not just the cost is the same, but two subsets are the same too). So the question is: What is A Gomory-Hu tree? There are two common definitions: 1)A flow equivalent tree. WebThe theory of graph cuts used as an optimization method was first applied in computer vision in the seminal paper by Greig, Porteous and Seheult [3] of Durham University. Allan Seheult and Bruce Porteous were members of Durham's lauded statistics group of the time, led by Julian Besag and Peter Green (statistician), with the optimisation expert ...

In graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. Any cut determines a cut-set, the set of edges that have one endpoint in each subset of the partition. These edges are said to cross the cut. In a connected graph, each cut-set determines a unique cut, and in some cases cuts are identified with their cut-sets rather than with their vertex partitions. In a flow network, an s–t cut is a cut that requires the source and the sink to be in different subsets…

For any cut C of the graph, if the weight of an edge e in the cut-set of C is strictly smaller than the weights of all other edges of the cut-set of C, then this edge belongs to all MSTs of the graph. So, it is not enough for an edge to belong to a cut set of any cut.
