On the decomposition of a graph into stars
WebIn graph theory, a split of an undirected graph is a cut whose cut-set forms a complete bipartite graph.A graph is prime if it has no splits. The splits of a graph can be collected into a tree-like structure called the split decomposition or join decomposition, which can be constructed in linear time.This decomposition has been used for fast recognition of … Web31 de jan. de 2024 · Problems of graph decomposition have been actively investigated since the 70’s. The question we consider here also combines the structure of a facility location problem (choosing the centres of the stars) with a max–min fairness optimization criterion that has recently received attention in resource allocation problems, e.g., the …

WebWe assume that p ≠ q, for otherwise it reduces to star –decomposition. Even then, if either p or q=1, the problem reduces to decomposition of complete graphs into paths and stars.[5] Hence p>2and q>3.Regi T.[ 3]gives the conditions for the S 2∪S 3 decomposability of K n and K m,n. In this paper the S p+1 ∪S Web1 de mai. de 2024 · In this paper, we propose a new conjecture that the complete graph \(K_{4m+1}\) can be decomposed into copies of two arbitrary trees, each of size \(m, m \ge 1\).To support this conjecture we prove that the complete graph \(K_{4cm+1}\) can be decomposed into copies of an arbitrary tree with m edges and copies of the graph H, …
WebOur technique is based on the decomposition of graphs into a set of substructures which are subsequently matched with the stable marriage algorithm. In this paper, we address the problem of comparing deformable 3D objects represented by graphs, we use a triangle-stars decomposition for triangular tessellations (graphs of 3D shapes). Web4 de mai. de 2024 · Let Sk and Kk respectively denote a path, a star and a complete graph on k vertices. By a -decomposition of a graph G, we mean a decomposition of G into …
Web21 de jan. de 2011 · A tree decomposition is a mapping of a graph into a related tree with desirable properties that allow it to be used to efficiently compute certain properties (e.g., independence polynomial) of the original graph. The tree decomposition of a graph is not unique and need not be isomorphic to the original graph. Tree decompositions are also … Web14 de abr. de 2024 · In this section, we introduce TKG completion methods proposed in recent years.
