I'm not sure what you mean by this. Could you elaborate?

The short answer is 'yes', the long answer is 'its complicated'. I'll
post code in a week or two and you can see what's going on for yourself.
>>Do you use 'yield' for backtracking?
No. But maybe I should. I'm still working out the most efficient way
to do backtracking. If you know any very efficient backtracking
algorithms, please let me know.
Thank you for your feedback,
