So if you need the code to run faster (by about the same order of magnitude), probably you can transform the critical part into C. I don't know much C at all, but I did use RubyInline for a few critical, but very simple methods. With that and Robert Klemme's BitSet, the program is efficient enough, now I just have to let it run for a while. Thank you once again for your help! -- Posted via http://www.ruby-forum.com/.
