Degree constrained minimum spanning tree
WebNov 9, 2024 · degree-constrained k-minimum spanning tree (DC k MST) problem which consists of finding a minimum cost subtree of G formed with at least k vertices of V where the degree of each vertex is less ... Weblocal minimum reached by the algorithm is not too bad. For the min degree spanning tree problem the solution space consists of all spanning trees. The connecting operation is to swap edges till the degree goes down. Formally: Definition 8.1.1 (T-swap:) Add edge e1 ∈/ T and remove edge e2 ∈ T s.t. e2 is on the unique

The problem of finding the Steiner tree of a subset of the vertices, that is, minimum tree that spans the given subset, is known to be NP-Complete. A related problem is the k-minimum spanning tree (k-MST), which is the tree that spans some subset of k vertices in the graph with minimum weight. A set of k-smallest spanning trees is a subset of k spanning trees (out of all p… WebExactly 1 component: If G ′ has exactly one component, we can compute T ′ = MST ( G ′), and then we just need to stitch v into T ′ using two edges. Find the cheapest edge incident on v and add this to T ′. Call this T ″. Now we have a …
