WebBiconnected graph: Any two vertices are joined by two vertex-disjoint paths. Triconnected graph: Any two vertices are joined by three vertex-disjoint paths. Tree: Connected graph without cycles. Rooted tree: Directed tree with a distinguished vertex, the root, such that each vertex lies on a directed path to the root. WebOct 6, 2008 · We determine the maximum number of edges in a connected graph with n vertices if it contains no path with k + 1 vertices. We also determine the extremal graphs.

WebIn the mathematical field of graph theory, a Hamiltonian path (or traceable path) is a path in an undirected or directed graph that visits each vertex exactly once. A Hamiltonian cycle (or Hamiltonian circuit ) is a cycle that … WebJan 25, 2024 · k is the number of paths to find. Using your programming language's form of infinity for d and k will give you all paths§. § obviously if you are using a directed graph and you want all undirected paths between s and t you will have to run this both ways: find_paths [s, t, d, k] find_paths [t, s, d, k] flower magic

WebMar 20, 2024 · Video. Given a directed graph where every edge has weight as either 1 or 2, find the shortest path from a given source vertex ‘s’ to a given destination vertex ‘t’. Expected time complexity is O (V+E). A Simple Solution is to use Dijkstra’s shortest path algorithm, we can get a shortest path in O (E + VLogV) time.
