The original description page was here. A tournament with more than two vertices is Hamiltonian if and only if it is strongly connected. An Eulerian graph G a connected graph in which cicuito vertex has even degree necessarily has an Euler tour, a closed walk passing through each edge of G exactly once.

From Wikimedia Commons, the free media repository. One possible Hamiltonian cycle through every vertex of a dodecahedron is shown in red — like all platonic solidsthe dodecahedron is Hamiltonian.

Hamiltonicity has been widely studied with relation to various parameters such as graph hamiltonianitoughnessforbidden subgraphs and distance among other parameters. Hamilton solved this problem using the icosian calculusan algebraic structure based on roots of unity with many similarities to the quaternions also invented by Hamilton.

Cifcuito of these results have analogues for balanced bipartite graphsin which the vertex degrees are compared to the number of vertices on a single side of the bipartition rather than the number of vertices in the whole graph. A Hamiltonian path or traceable path is a path that visits each vertex of the graph exactly once.

Retrieved 27 May Despite being named after Hamilton, Hamiltonian cycles in polyhedra had also hamiltooniano studied a year earlier by Thomas Kirkmanwho, in particular, gave an example of a polyhedron without Hamiltonian cycles.

From Wikipedia, the free encyclopedia. Once the review has been completed, this template should be removed. A Hamilton maze is a type of logic puzzle in which the goal is to find the unique Hamiltonian cycle in a given graph. The above theorem can only recognize the existence of a Hamiltonian path in a graph and not a Hamiltonian Cycle. Views Read Edit View history. Antonio78 grants anyone the right to use this work for any purposewithout any conditions, unless such conditions are required by law.

Determining whether such paths and cycles exist in graphs is the Hamiltonian path problemwhich is NP-complete. Description Grafo con circuito hamiltoniano. Interlanguage link template link number.

The number of vertices must be doubled because each undirected edge corresponds to two directed arcs and thus the degree of a vertex in the directed graph is twice the degree in the undirected graph. Any Hamiltonian cycle can be converted to a Hamiltonian path by removing one of its edges, but a Hamiltonian path can be extended to Hamiltonian cycle only if its endpoints are adjacent.

These counts assume that cycles that are the same apart from their starting point are not counted separately. Retrieved from ” https: All Hamiltonian graphs are biconnectedbut a biconnected graph need not be Hamiltonian see, for example, the Petersen graph.
