Thanks for resstarting and putting CS in the pool. I'm verry impressed by CS (is it CrazyStone like I think ?) It play extremly quickly (finish the game without having consumed time...) and very well. It's too much for my poor bot... but it's good for me, there is plenty of rooms for improvements

[computer-go] Playout acceleration

Has anyone tried heavy, slow playouts near the tree and light, fast playouts near the end of the game? I'm calling this "playout acceleration" because it starts slow and speeds up. You could have many different playout weights/speeds in a single playout. It seems like a reasonable idea to me si

You would have to ask these questions of Paul. He is an extremely serious and careful person, so while I would find it hard to believe that every person had exactly the same rating down to 0.01, it must have been very close when the entire collection of AGA members was considered. I do not
