Circuits and trees in oriented linear graphs

WebTwo operations for augmenting networks (linear graphs) are defined: edge insertion and vertex insertion. These operations are sufficient to allow the construction of arbitrary nonseparable networks, starting with a simple circuit. The tree graph of a network is defined as a linear graph in which each vertex corresponds to a tree of the network, and … 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.

A directed graph is called an oriented graph if none of its pairs of vertices is linked by two symmetric edges. 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… WebGraph Theory and Trees Graphs A graph is a set of nodes which represent objects or operations, and vertices which represent links between the nodes.

WebOne definition of an oriented graph is that it is a directed graph in which at most one of (x, y) and (y, x) may be edges of the graph. That is, it is a directed graph that can be formed as an orientation of an undirected (simple) graph. Some authors use "oriented graph" to mean the same as "directed graph".
