Hamiltonian Cycle Detector

I am interested in the Hamiltonian Cycle problem. I have built some simple tools in Perl, to visualize graphs, and to attempt to solve the Hamiltonian Cycle problem in polynomial time, for a user-entered graph. This is an early prototype of the algorithm, which is a work-in-progress, on its way to becoming a CPAN module.

Here is a relatively complex graph being evaluated by the Hamiltonian Graph Detector. This script often simplifies the input graph by removing vertices and edges, according to certain rules. Also, the Hamiltonian Graph Detector generates isomorphs of the input graph. All transforms are done while preserving the is_hamiltonian() property.
