In this paper, various properties of some planar regular sub graphs of various degrees of the complete graph K2m+2 for m≥2 have been discussed. An algorithm has been developed to find out the least cost route (minimum weighted Hamiltonian circuit) of traveling salesman problem with the help of these sub-graphs.
