Hi, On the topic of markers, attached is what I did when a year back when I was still interested in Go I am not at all saying that this is the best way to do it (there is a bit of overhead), but it is a cute trick that should bring a smile or two. Joel On Thu, Oct 30, 2008 at 9:40 PM, Mark

Hi Claus, In sum, there doesn't seem to be a good basis for understanding playouts and their optimisation, other than by trial and error. Those who've been through some cycles of trial-and-error probably have at least a vague intuition of what works and what doesn't (or didn't when they last

Hi Ivan, I like to view game tree search methods as a systematic ways to correct static evaluation errors. I don't find it surprising that UCT scales well with increasing time and space. I claim that the accuracy of the monte-carlo method increases as we get closer to the end of a game. UCT helps

Hi Christoph, I have been thinking about making a version of Goanna (~2250 on CGOS) public, once it plays in a human friendly way. At the moment, it is nearly unusable for fun human vs computer matches because of a lack of opening book (slow first few moves), and ridiculous endgame play.
