## Caminho (teoria dos grafos)

A Hamiltonian cycle or Hamiltonian circuit is a Hamiltonian path that is a cycle. 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. For the question of the existence of a Hamiltonian path or cycle in a given graph, see Hamiltonian path problem. The original description page was here.

Antonio78 at Italian Wikipedia. This work has been released into the public domain by its author, Antonio78 at Italian Wikipedia. One possible Hamiltonian cycle through every vertex of a dodecahedron is shown in red — like all platonic solidsthe dodecahedron is Hamiltonian. Retrieved from ” https: All cricuito user names refer to it. PD-user All media needing categories as of Files moved from it.

For details about this file, see below. A tournament with more than two vertices is Hamiltonian if and only if it is strongly connected.

Grafo con circuito hamiltoniano. A graph that contains a Hamiltonian path is called a traceable graph. Please help improve this media file by adding it to one or more categories, so it may be circuiyo with related media files how? Grafo con evidenziato un circuito hamiltoniano. This article is about the nature of Hamiltonian paths. This page was last edited on 29 Septemberat Hamiltonian paths and cycles are named after William Rowan Hamilton who invented the icosian gamenow also known as Hamilton’s hamiltoinanowhich involves finding a Hamiltonian cycle in the edge graph of the dodecahedron.

A Hamiltonian cycleHamiltonian circuitvertex tour or graph cycle is a cycle that visits each vertex exactly once except for the vertex that is both the start and end, which hamiltonisno visited twice. The above theorem can only recognize the existence of a Hamiltonian path in a graph and not a Hamiltonian Cycle.

Similar notions may be defined hamiltoniaano directed graphswhere each edge arc of a path or cycle can only be traced in a single direction i. By using this site, you agree to the Terms of Use and Privacy Policy. Archived from the original on 16 April All source information is still hamiltoniiano.

This page was last edited on 23 Marchat Any Hamiltonian cycle can be converted to hamiltniano Hamiltonian path by removing one of its edges, but a Hamiltonian path can be extended to Hamiltonian cycle only if its endpoints are adjacent. Knight’s Tours”, Across the Board: A Hamilton maze is a type of logic puzzle in which the goal is to find the unique Hamiltonian cycle in a given graph.

Hamiltonixno whether such paths and cycles exist in graphs is the Hamiltonian path problemwhich is NP-complete. Retrieved 27 May Despite being named after Hamilton, Hamiltonian cycles in polyhedra had also been studied a year earlier by Thomas Kirkmanwho, in particular, gave an example of a polyhedron without Hamiltonian cycles.

This tour corresponds cicruito a Hamiltonian cycle in the line graph L Gso the line graph of every Eulerian graph is Hamiltonian. As complete graphs are Hamiltonian, all graphs whose closure is complete are Hamiltonian, which is the content of the following earlier theorems by Dirac and Ore. Hamiltoniabo Wikipedia, the free encyclopedia. All Hamiltonian graphs are biconnectedbut a biconnected graph need not be Hamiltonian see, for example, the Petersen graph.

Many 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. These counts assume that cycles that are the same apart from their starting point are not counted separately. In other projects Wikimedia Commons. Hamiltonicity has been widely studied with relation to various parameters such as graph densitytoughnessforbidden subgraphs and distance among other parameters.

Public domain Public domain false false. An Eulerian graph G a connected graph in which every vertex has even degree necessarily has an Euler tour, a closed walk passing through each edge of G exactly once.
