Prunning Strategies to compute the total number of hamiltonian paths in 2D grid?

There is an O(n^2 * 2^n) solution that works for general graphs. The structure is identical to the O(2^n * n^2) algorithm described here algorithmist.com/index.php/Traveling_Sal... Except rather than recording minimum distances, you are recording counts Any pruning you can do on top of that will still help.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
