Is minimum spanning tree np-complete
Witryna12 gru 2012 · yes , the document you showed tells sorting as a decision problem is NP-Complete. It means a program can make a decision Yes/No. The question above posted asks if sorting is P or NP which is actually undefined since only decision problems comprise of P and NP and sorting isn't part of any! WitrynaShow that the following two problems are NP-hard: G has a spanning tree where every node has at most k neighbors, and k is part of the input. G has a spanning tree …

WitrynaThe problem of finding a Hamiltonian cycle in a graph is NP-complete. Theorem 10.1: The traveling salesman problem is NP-complete. Proof: ... First, we create a minimum spanning tree the weight of which is a lower bound on the cost of an optimal traveling salesman tour. Using this minimum spanning tree we will create a tour the cost Witryna1 Answer Sorted by: 2 The maximum leaf spanning tree (MLSPT) is equivalent to the minimum connected dominating set (MCDS), see here. So we just need to prove MCDS is NP-complete. It's easy to verify that the decision version of MCDS is in NP.
A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. That is, it is a spanning tree whose sum of edge … Zobacz więcej Possible multiplicity If there are n vertices in the graph, then each spanning tree has n − 1 edges. There may be several minimum spanning trees of the same weight; in particular, if all the edge … Zobacz więcej Alan M.

WitrynaThis can be shown by a reduction from the Hamiltonian path problem. It remains NP-complete even if k is fixed to a value ≥ 2. If the problem is defined as the degree must be ≤ k, the k = 2 case of degree-confined spanning tree is the Hamiltonian path problem.

Witryna18 paź 2014 · 2 Answers. A leaf is a vertex of degree one in a tree. The degree of a vertex is equal to the number of edges that contain the vertex. A minimum leaf spanning tree is a problem that given a graph G = (V, E) and an integer i, is there a spanning tree T in G that contains at most i leaves? By definition, a leaf here means …
