Graf hamiltonian
WebAug 30, 2011 · An hamiltonian path is certainly NP-complete. However, an hamiltonian walk which can visit edges and vertices more than once (yes it's still called hamiltonian … A Hamiltonian path or traceable path is a path that visits each vertex of the graph exactly once. A graph that contains a Hamiltonian path is called a traceable graph. A graph is Hamiltonian-connected if for every pair of vertices there is a Hamiltonian path between the two vertices. A Hamiltonian cycle, Hamiltonian circuit, vertex tour or graph cycle is a cycle that visits each vertex exactly once. A graph that contains a Hamiltonian cycle is called a Hamiltonian graph.

WebMay 11, 2024 · Try every permutation of vertices, and if one of the permutations is a cycle, then the graph is Hamiltonian. If so, you get a certificate. If no permutation was a cycle, the graph is not Hamiltonian. You cannot convince your friends that the graph is non-Hamiltonian without trying all permutations*.

WebGrafuri Hamiltoniene. Sunt grafurile ce conțin un traseu (ciclu) care vizitează toate nodurile și care revine în nodul de pornire fără a trece printr-un nod de două ori (traseu numit ciclu hamiltonian). Problema determinării ciclului hamiltonian este una NP-completă (NP = non polynomial) în cazul unui graf oarecare. Aici prezentăm ... WebCiclu hamiltonian de cost minim Se dă un graf orientat cu N vârfuri şi M muchii, fiecare arc având asociat un cost. Un ciclu al acestui graf se numeşte hamiltonian dacă conţine fiecare nod din graf exact o singură dată. Un graf care conţine un astfel de ciclu se numeşte graf hamiltonian. Costul unui ciclu este egal cu suma arcelor aflate pe ciclu.
