Dear Bill, Thanks for your feedback. I would certainly appreciate seeing any further work of you in this area!

However, there are many smarter approaches out there, not only genetic algorithms. For example, constraint propagation can reduce the size of the search space by orders of magnitudes. Also, the order in which variables are visited can have a similar impact. Here is a link to a book chapter I wrote for musical problems on the latter factor (draft version of [1]). http://cmr.soc.plymouth.ac.uk/tanders/publications/Anders-VariableOrderings-2011-draft.pdf If you are looking for highly efficient and flexible constraint solver you may want to check out http://www.gecode.org/.
