WebIn the graph in Figure 6, eand e0are bridges. Note that eulerian graphs are bridgeless (why?). Analogous statement for di-graphs holds as well. Figure 6: Graph with bridges eand e0. A subgraph of Gis called component of Gif it is a maximal connected sub-graph of G. (Note: A maximal connected subgraph cannot be enlarged by adding vertices/edges. WebMay 15, 2024 · The core functions in gif package are hgt and sgt. These functions based on graphical independence filtering have several advantages: It’s applicable to high-dimensional multivariate data and is comparable to or better than the state-of-the-art methods in respect to both graph structure recovery and parameter estimation.
