No game have started for half an hour, so it seems to have a problem. And if some other people want to play on 13x13 don't be afraid, my bot will be happy to play with yours. Tom -- Thomas LavergneEntia non sunt multiplicanda praeter

[computer-go] Playout acceleration

2008-09-05 Thread Michael Williams
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

There is this: http://webdisk.lclark.edu/drake/publications/GAMEON-07-drake.pdf The idea of gradual acceleration is intriguing, although I shudder to think of setting the parameters for such a process. Peter Drake http://www.lclark.edu/~drake/ On Sep 5, 2008, at 10:43 AM, Michael

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

There might be no need for heavier playouts to be slower. Sometimes they are even faster. (maybe it was in case of Crazy Stone?) On Fri, Sep 5, 2008 at 18:43, Michael Williams [EMAIL PROTECTED] wrote: Has anyone tried heavy, slow playouts near the tree and light, fast playouts near the end of

Yes, I tried heavy playouts for N plys, then switching to light.?It didn't really speed things up all that much but it weakened my bot quite a bit, on a per playout basis, resulting in a clear net loss. ? I tried ladder reading for the first N plys, then no ladder reading. The results were
