✍ Roberto Cordone; Francesco Maffioli 📂 Article 📅 2004 🏛 Elsevier Science 🌐 English ⚖ 270 KB

This paper concerns the optimal partition of a graph into p connected clusters of vertices, with various constraints on their topology and weight. We consider di erent objectives, depending on the cost of the trees spanning the clusters. This rich family of problems mainly applies to telecommunicati

A graph G admits a tree-partition of width k if its vertex set can be partitioned into sets of size at most k so that the graph obtained by identifying the vertices in each set of the partition, and then deleting loops and parallel edges, is a forest. In the paper, we characterize the classes of gra
