Thanks for your replies. In response to DrEvil, I was wondering if there is some sort of algorithm for generating regions and if not maybe how one would go about implementing it (I get the general idea, but am totally clueless on details such as region size, etc.). I also implemented a C-based Priority Queue and it did speed up the search a little but not too much more. I think the regions/sectors idea will probably work, so if you could just give me a slight push in the right direction (maybe even a small code sample) it would help me immensely. Thanks guys.
