Approximating the Degree-Bounded Minimum Diameter Spanning Tree ProblemWe consider the problem of finding a minimum diameter spanning tree with maximum node degree . in a complete undirected edge-weighted graph. We prove that the problem is NP-complete, and provide an .-approximation algorithm for the problem. Our algorithm is purely combinatorial, and relies on a combination of . and ..

https://doi.org/10.1007/978-94-009-5878-4nimize the total absolute weight of cut positive edges and uncut negative edges. Thus, large positive weights (representing strong correlations between endpoints) encourage those endpoints to belong to a common cluster; large negative weights encourage the endpoints to belong to different clusters;
