WebA path in a graph G is a subgraph of G that is a path graph (West 2000, p. 20). The length of a path is the number of edges it contains. In most contexts, a path must contain at least one edge, though in some applications (e.g., defining the path covering number), "degenerate" paths of length 0 consisting of a single vertex are allowed (Boesch et al. … WebLet G = (V;E;w) be a weighted undirected graph. A random walk on a graph is a process that begins at some vertex, and at each time step moves to another vertex. When the …
