Hamiltonian Cycle: Simple Definition and Example

WebDefinition 1. A Hamilton's cycle is a graph cycle in which every vertex of a graph is passed only once (except the first vertex). Hamilton's path is a graphical path that visits each vertex exactly once. Finding a Hamilton's cycle with a minimum of edge weights is equivalent to solving the salesman problem.

WebA graph G has a Hamiltonian Circuit if there exists a cycle that goes through every vertex in G. We want to show that there is a way to reduce the vertex cover a graph with a vertex cover, to a graph with a hamiltonian circuit. To do this we will construct a graph G 0, so G has a vertex cover of size k if and only if G has a hamiltonian circuit.
