Among directed graphs, the oriented graphs are the ones that have no 2-cycles (that is at most one of (x, y) and (y, x) may be arrows of the graph). A tournament is an orientation of a complete graph. A polytree is an orientation of an undirected tree. Sumner's conjecture states that every tournament with 2n – 2 vertices contains every polytree w… dfat travel advice malaysia

"WebThis paper describes a new method of finding all the Hamiltonian circuits in an undirected graph, if such circuits exist. The method uses for the first time the mesh description of a graph and it is here applied in cubic graphs. A process to test Hamiltonicity, which runs in linear time, had been derived.

WebA linear graph is defined as a collection of various nodes and branches. A node is defined as a common point at which two or more branches meet together. A branch is a line joining two nodes which represents a circuit element. A graph of any network can be drawn by placing all the nodes which are points of intersection of two or more branches.
