Traversing a graph such that not an edge is repeated but vertex can be repeated and it is closed also i.e. it is a closed trail. Vertex can be repeated. Edge can not be repeated. Here 1->2->4->3->6->8->3->1 is a circuit.

WebMar 24, 2024 · Eulerian: this circuit consists of a closed path that visits every edge of a graph exactly once; Hamiltonian: this circuit is a closed path that visits every node of a graph exactly once.; The following image exemplifies eulerian and hamiltonian graphs and circuits: We can note that, in the previously presented image, the first graph (with … WebHamiltonian circuit is also known as Hamiltonian Cycle. If there exists a walk in the connected graph that visits every vertex of the graph exactly once (except starting vertex) without repeating the edges and returns to the starting vertex, then such a walk is called as a Hamiltonian circuit. OR. If there exists a Cycle in the connected graph ...
