Graphical steiner tree
WebSep 1, 2024 · There exists an unique Steiner tree minimal for inclusion, hence it is sufficient to test if it is without conflicts. Theorem 10 Given (G, M, C) a graph with conflicts and a subset of vertices, deciding whether there exists a STwnC is NP-complete even if G is a split graph and C a graph of maximum degree 1 and of stretch 1. WebApr 1, 1993 · A standard set of graph problems used extensively in the comparison of Steiner tree algorithms has been solved using our resulting algorithm. We report our results (which are encouragingly good) and draw conclusions. Download to read the full article text Author information Authors and Affiliations
