Abstract: |
A VC-algorithm to obtain the vertex covering of a graph is presented. The VC representative and full closed chain of the graph are defined. It is proved that a connective graph is Hamiltonian graph if and only if there is a full-closed chain in it's VC representative. A proof is also given to some other theorem and inferences which are very useful in constructing a full closed chain. |
