Simple paths in a graph

WebbWe will prove that G has a Hamiltonian path by using the following theorem, known as Dirac's theorem: Dirac's Theorem: Let G be a simple graph with n vertices, where n>=3. If every vertex in G has degree at least n/2, then G has a Hamiltonian cycle. In our case, G has 2k+1 vertices, so n=2k+1. Since G is k-regular, each vertex in G has degree k. WebbA complete graph is a graph where all vertices are connected to all other vertices. A Hamiltonian path is a simple path that contains all vertices in the graph. Show that any complete graph with 3 or more vertices has a Hamiltonian path. How many Hamiltonian paths does a complete graph with n vertices has? Justify your answer.

WebbGenerate all simple paths in the graph G from source to target, starting from shortest ones. A simple path is a path with no repeated nodes. If a weighted shortest path search is to be used, no negative weights are allowed. If it is a string, it is the name of the edge attribute to be used as a weight. If it is a function, the weight of an edge ... WebbDefaults to all vertices.
