Andrew, I'm interested in the HCP algorithms you're using - your paper 
seems slightly coy about them! You mention LKH, Snakes and Ladders and 
Concorde, but as far as I'm aware, these don't exhaust the search space 
so may miss solutions. However, your paper claims to have exhaustively 
searched many of the part structures and determined the exact number of 
solutions available, so presumably you didn't use these algorithms? You 
mention an algorithm by Chalaturnyk that *is* exhaustive - did you use 
this, or something else?
