WebNov 24, 2014 · If the Hamiltonian path is not randomized enough, go to step 3. Only the start and the end will not move. To randomize the end or the start, you can replace the initial zigzag by another algorithm: Choose one of the four corners Search all the non-visited neighbors If there is no neighbor, the map is filled, otherwise go to step 4 WebSince it is a linked graph, the possibility of a Hamiltonian route exists inside it. Since none of the graphs in the degree sequence 0,3,1,1 are linked, it is impossible for any of them to have a Hamiltonian route. All graphs with a degree sequence of 0,0,6 are not connected and therefore cannot have a Hamiltonian path. images of indian football players with nameWebAs mentioned in the other answer by Gerry Myerson, there is no simple neccessary and sufficient condition, since the problem of determining if a general graph has a Hamiltonian Path is NP-complete.
