Re: [Computer-go] Vol 69, Issue 5 hoping for a respect as the lottery win
. Aretha Franklin wanted r-e-s-p-e-c-t, but frankly, my dear, i don't give a damn. this note is not a riposte to the latest epistle in a stream of libelous personal abuse, but a clarification intended to stimulate thought among any young-at-hearts that may also subscribe to this forum. why would anyone want to program a computer to play an old board game? different people have different reasons because they have different motivations. for some, most notably Arthur Samuel, the attraction is self-evidently the kudos of fathering an electronic alter-ego that has a chance of achieving fame and glory by becoming the alpha male through gladiatorial olympic combat on the world's stage; the same motivation that led IBM to spend quite a lot of advertising budget to beat Gary Kasparov. for others like Jacques Pitrat, it is mathematical inquisitiveness. i mention these two because Pitrat overrode Samuel's veto of my IJCAI 79 paper on the grounds that i hadn't proved my fledgeling ideas by writing a program like he had done in 1952 (which did little more than demonstrate that Johnnie von N's 1928 minimax theorem was right in the first place). Thanks, Jacques! btw, i didn't find out about my debt of gratitude to Pitrat until decades later when Feigenbaum's old archives were digitised and put on the web. and for yet others, myself included, computer Go is a convenient experimental testbed for scientific enquiry into the nature of intelligence, following a path trodden by pioneers like John von Neumann, Alan Turing and Herbert Simon. Go is a convenient testbed for theoretical AI research because it is a narrowly-scoped information domain, one free from the foggy hairyness of the physical world, which thereby enables one to ponder on experimental models of knowledge representation and processing without becoming bogged down by also having to distinguish signal from noise, a significant hurdle that real-world robots have to confront. ___ Computer-go mailing list Computer-go@computer-go.org http://computer-go.org/mailman/listinfo/computer-go

I would like to encourage readers of djhbrown's posts who don't see any actual contribution to computer go discussions in these posts to ignore them, either by technical means or just not replying to them. As long as there are replies (of *any* kind), that demonstrates interest (and consequently value) to both the original poster (encouraging further posts) and moderators.

[Computer-go] kgsGtp 3.5.20 has a problem?
Hi, Today I lost all games on time in KGS tournament. Sorry I did not check well. Today I replaced latest kgsGtp 3.5.20. And looks like kgsGtp stops after sending "time_left" command. I found some people have reported this problem. new kgsGtp client does not work for me, tournament soon http://computer-go.org/pipermail/computer-go/2014-November/006947.html http://computer-go.org/pipermail/computer-go/2015-July/007740.html kgsGTP client http://computer-go.org/pipermail/computer-go/2015-September/007914.html kgsGtp 3.5.10 works well. I put kgsGtp 3.5.10. http://www.yss-aya.com/kgsGtp-3.5.10.tar.gz Regards, Hiroshi Yamashita - <--list_commands -->=--> -->protocol_version ... --> <--name -->=--> --> <--version -->=--> --> <--boardsize 19 -->=--> --> <--time_settings 2850 0 0 <--boardsize 19 -->=--> --> <--clear_board -->=--> --> <--komi 7.5 -->=--> --> <--time_settings 2850 0 0 -->=--> --> <--genmove b -->=--> -->R17--> <--time_left b 2699 0 -->=--> --> java.lang.NullPointerException at com.gokgs.client.gtp.y.a(kgsgtp:22) at com.gokgs.client.gtp.z.a(kgsgtp:58) at org.igoweb.igoweb.client.gtp.aT.a(kgsgtp:107) at org.igoweb.igoweb.client.gtp.aM.b(kgsgtp:85) at org.igoweb.igoweb.client.gtp.aa.a(kgsgtp:246) at org.igoweb.igoweb.client.gtp.c.a(kgsgtp:395) at org.igoweb.igoweb.client.gtp.c.a(kgsgtp:378) at org.igoweb.igoweb.client.gtp.c.d(kgsgtp:368) at org.igoweb.igoweb.client.gtp.ad.a(kgsgtp:164) at org.igoweb.igoweb.client.gtp.c.a(kgsgtp:158) at org.igoweb.igoweb.client.gtp.al.a(kgsgtp:48) at org.igoweb.igoweb.client.gtp.am.a(kgsgtp:431) at org.igoweb.igoweb.client.gtp.aq.run(kgsgtp:298) at org.igoweb.igoweb.client.gtp.at.a(kgsgtp:18) at org.igoweb.igoweb.client.gtp.au.run(kgsgtp:97) at java.lang.Thread.run(Unknown Source) ___ Computer-go mailing list Computer-go@computer-go.org http://computer-go.org/mailman/listinfo/computer-go
Re: [Computer-go] Detlef's DCNN data
Hi Aja, I think (1) is what you are doing, if I understand correctly. Did you ever try (2)? I imagine you might already have tried it (maybe it's bad?) because it's a really easy experiment. Yes, I did (1). I did not try (2), but I will.

I multiply it by 1000, and multiply it by each move's rating. (r *= 1000 means multiply by 1000). Aya calls DCNN when node is created. Aya makes 900 nodes in 1 playouts. GTS 450 needs 17.4ms for a position. 900*17.4 = 15.6 sec is needed. Aya needs 5 sec for 1 playout without DCNN, and 20.6 sec with DCNN. So 4 times slower. Did you try only using CNN's prior as described in our CNN paper? That is to say, For every legal move on the board, 1. Mix MM gamma values with CNN prior by treating CNN's probability p as gamma value 1000 * p. 2. Use CNN's p. I think (1) is what you are doing, if I understand correctly. Did you ever try (2)?
