Today, I might come up with a better algorithm, but back then, all I could find was a brute-force approach. The most complex puzzle I had seen at the time was taking hours to run. I bet that you could come up with a better algorithm now, even in VB6 if you had to, to get the run time down. I've seen people take "optimised" C solutions that run in hours and make them run in minutes, just by rewriting the algorithm and rethinking basic assumptions.
