At some point I'll post something with some meat to it, but to sum it up, I'm not nearly as optimistic about it as I once was. In my experience, TDLeaf can train the material weights, and it can even produce an evaluation vector that's superior to a 'material only' vector. I am not convinced it's useful for training a complex vector, nor am I convinced it does a better job than hand tuning. For that matter, I am not even convinced it converges to the optimal vector! Caveat: it's possible (though I think it's unlikely) that my implementation is flawed. My engine will become open source at some point (maybe after the next CCT), so you can judge for yourself then. Will Singleton and I had a bet on this... I conceited defeat the other day. THe original bet was for the loser to fly the winner and spouse across country for drinks. :) I'm pretty sure Will's decided he'll forego that if I show up at a tourney, but that's his call. I'm still very interested in learning algorithms, but I'll be focusing on improving my evaluation for a while. Again- I will post some data at some point. -- James
