I did a test a while back and changed the benchmarking to use no virtual functions. The result was less than 2% faster (I'm using cygwin, by the way). So, not a big deal there. I also use exceptions to terminate searches. I have no idea how much of a slowdown this causes, but I doubt I'd change anyway. Exceptions make this so easy and flexible. There's also a rather complicated template buried in there -- but that was more of a programming exercise than a necessity. :) For me, the bottom line is that the resulting program is easier to work with, perform horrible experiments on, etc. And this more than makes up for any slight slowdown. -paul
