Re: [computer-go] cgos viewer feature request
Nothing to apologize over! I probably should have put some kind of column headings or something. I thought it more useful to be a count-down timer - it's much easier to calculate how much time you took by subtraction with the previous entry than it is to see how much time is left by adding up every entry. - Don Hideki Kato wrote: Hi Don, Now I understand the time is the time left!

Does 04:19 mean 41.9 seconds? Hideki Hi Hideki, 04:19 means 4 minutes and 19 seconds.I don't understand how it could mean 41.9 seconds. Is this an international thing?Is there a better way that's more understood than what I am doing? If so, all clients on 9x9 should lose by time. But now I'm sure that the time is completely wrong. Please check your code. Hideki - Don Don Dailey: [EMAIL PROTECTED]: I just updated the current viewer to version 0.35. I added the remaining time display. The default server is the 19x19 server, so if you use it for 9x9 you must specify the server and port. You must use the options like this: cgosview -server server_name -port portnum -games 1,2,3,4,5 Games is optional, but it will pop up all the specified games. - Don Jason House wrote: On Thu, 2007-11-01 at 17:05 -0400, Don Dailey wrote: The source code is included - even though you probably don't realize it.There is a utility that will unpack the kit and reveal the source code.

(I hope, I'm just figuring this out now) You'll need to download tclkit from [1] and sdx from [2]. sdx assumes it can find tclkit, so after unpacking, you must rename it. Similarly, sdx will download as sdx.kit and the instructions I found say to rename it to sdx. The sdx unwrap (and wrap) should then be all that's needed to access the source.

[computer-go] Rapid action value estimation
I'd like to implement RAVE as described in [1]. I believe I have a very clear understanding of how to do this at the leaves of the UCT search tree. What I'm not sure about is how to apply RAVE results higher in the UCT tree. Does anyone have any experience with this that they're willing to share?

Of course, you need to be careful with signs :-) Btw, I don't really see a point in calculating and adding the confidence bound for RAVE as well, as all moves will have been played almost equally often - thus I dropped the term.. Maybe Sylvain or someone else can comment on this.. Another thing - I didn't believe that you need to do RAVE seperately for both colors (i.e. you should only consider later moves on the point by the same color), as e.g. Peter Drake mentioned in a paper of his. But after some experiments I changed my mind and think he is right =) Cheers, Benjamin On 11/2/07, Jason House [EMAIL PROTECTED] wrote: I'd like to implement RAVE as described in [1].

Re: [computer-go] Rapid action value estimation
I store it in the normal uct tree, so that each node has variables raveVisits and raveWins besides uctVisits and uctWins. So a node in the UCT-DAG can either represent a position or a move.
