IaGoChall [-\]: so, we finish the last test : it will begin in a few minutes (about ten)
IaGoChall [-\]: we don't know the colors for the moment : there will be a nigiri
IaGoChall [-\]: chinese rules, 7,5 komi
IaGoChall [-\]: Catalin is saying he's quite scared about the game, because he saw the program playing against Farid Ben Malek before
IaGoChall [-\]: nigiri is up : mogo is black !

IaGoChall [-\]: yes, of course
Hydro47 [15k\]: How is the game being held? is Taranu on a computer, or is it geting relayed to him by another person?
IaGoChall [-\]: it's getting relayed on a real goban
IaGoChall [-\]: black is disconnected...
micromegas [5k\]: what? the game is finished?

iam2k [2k\]: ...
Warfreak2 [3d\]: how many simulations is mogo doing, per move?
Sparkster [3d\]: mogo version 3 on my computer looks stronger >.<
Sparkster [3d\]: weird
Warfreak2 [3d\]: mogo always looks weaker than it is
Schelling [1d\]: moderated?
eboesch [1k\]: My bet is it didn't recognize g9 as an eye
Warfreak2 [3d\]: eboesch, mogo doesn't recognise anything as an eye, it does not know what an eye is
eboesch [1k\]: it has an own-eye-filling rule though, so it does sort of
Warfreak2 [3d\]: the only things about go it knows are the capture rule, the ko rule, and how to score a game
Irrdan [5d\]: wonder why it didnt see c8
HG [4k\]: Yes. Mogo is one of those new generation go playing programs that plays out random games to evaluate a situation.
Warfreak2 [3d\]: it probably did see c8
eboesch [1k\]: it also uses patterns
Dima12333 [2k\]: :P
Warfreak2 [3d\]: but it realised that it lost whatever it played, and certainly lost if it defended at d9
Dima12333 [2k\]: Mogo gonna lose :[[[[[[[[[[[[
Irrdan [5d\]: really warfreak?!
ikami [1k\]: can a bot progress ?
Warfreak2 [3d\]: irrdan, that's how mogo works
Irrdan [5d\]: cool
Warfreak2 [3d\]: it will never play a move that loses with 100% chance
qwazidan [4k?\]: self--atari requires the opponent to capture
Warfreak2 [3d\]: also it will play any move that wins with 100% chance, even if it is an otherwise stupid move like filling its own territory
Warfreak2 [3d\]: that is why mogo almost always wins by 0.5 exactly
Warfreak2 [3d\]: not because you "almost" beat it, it just didn't feel like winning by more.
eboesch [1k\]: true
Irrdan [5d\]: this makes mogo an interesting opponent
Warfreak2 [3d\]: it also makes mogo terrible at handicap go
buggler [2k\]: lol
Warfreak2 [3d\]: because it doesn't mind losing 8 of its 9 stone advantage by move 20
Irrdan [5d\]: haha
Warfreak2 [3d\]: as long as it still thinks it can't lose, which of course it can as its opponent is stronger
Warfreak2 [3d\]: and if it is giving handicap, it thinks it can't win, which of course it can, so it just plays the craziest move it can find
pasky [-\]: warfreak: technically, you are not right, current UCT programs know atari, ladders and can match some patterns like hane at the head of two stones
pasky [-\]: improving the quality of playouts is one of the main areas of research nowadays
mmpl: improving the quality of playouts is pretty nebolous territory.
Warfreak2 [3d\]: sure, mogo is more complicated than just playing things out randomly, but nonetheless it strives to maximise win probability, rather than win margin
pasky [-\]: yes
pasky [-\]: yeah, improving the quality of playouts is black magic
Warfreak2 [3d\]: and it does not take into account that its opponent may be much stronger or much weaker
mmpl: In exploration/exploitation optimization there is a right level of random noise.
mmpl: It is surprisingly high
eboesch [1k\]: It just needs to be high enough to include the correct move when the heuristics guess the wrong one :)
mmpl: too low and the cost of search and re-search will kill a bot
Hilarius [2k\]: is not over yet?
XenoQ [5k\]: Mogo resigned
gammaburst: Did MoGo smile when it resigned?  :)
Warfreak2 [3d\]: mogo is always smiling
ginji [6k\]: what's happenning?
Warfreak2 [3d\]: the game ended, mogo was black, and resigned
Warfreak2 [3d\]: the next game will start soon
Warfreak2 [3d\]: in a different demo game
Warfreak2 [3d\]: see iagochall's game list
XenoQ [5k\]: ah, I thought it will be here so I am waiting here..lol
XenoQ [5k\]: :D
saymon59 [8k\]: the game is over?
danny3889 [17k\]: what time is the game tomorrow?
danny3889 [17k\]: it says 10AM, but what time zone is that?
