WebApr 22, 2024 · If the cup property is false, then there's a graph and there's an edge, which actually is the cheapest crossing some cut, and yet, that edge does not belong to the minimum cost spanning tree T star. The plan then is to exchange this missing edge E with some edge that isn't a tree T star, which is more expensive, thereby getting a better ...

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.
