Hamiltonian graph theorem
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 ... WebHamiltonian graphs are used for finding optimal paths, Computer Graphics, and many more fields. They have certain properties which make them different from other graphs. …
