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 … Web6 de abr. de 2013 · For i ∈ {0, …, k − p 2 − 1}, we construct the star S (i) ...
