Re: Go has fallen to computer domination?

Three of the team members have now said they are 'quietly confident' for the Lee Sedol match, which makes me think they must have something now they didn't use for the previous match. I don't think they would say that if the ELOs are to come from bigger hardware only. Re-training the networks requi...

Re: Go has fallen to computer domination?

At least in chess, just not making any large mistakes and exploiting any of the opponent's large mistakes is worth a lot of rating points. GMs blunder all the time. They mis-remember openings. They overlook shallow combinations. They exchange into losing endgames. They fail to find key moves that a...

Re: Go has fallen to computer domination?

What's this Go thing? ... Hi Vincent, Welcome back! Fabien. Allo allo allo! Just checking the status of this match. In 2007 against a very angry professional Chinese go lady i said that computer would win sooner from the best 9-dan player than they'd guess because the human has one weakness that th...

Re: Go has fallen to computer domination?

Hah i doubt they can play blitz games easily with a big hardware setup. Typically starting up clusters with gpu's attached you need a specific overhead in time. For example the SGI 3800 machine i ran at in 2003 it took 3 hours just to startup Diep initially. So that was just typing: "diep" followed ...

Re: Go has fallen to computer domination?

Because that implied that there was a lot to win in terms of search depth Uri. They were forward pruning in the root back then and optimistically claimed 1 dan level with that (amateur dan). Note i posted some years later some of the results i had seen. Namely that nullmove worked far better in go t...

Re: Go has fallen to computer domination?

What's this Go thing? google has alphago and how realistic is this facebook program darkforest? Who are the programmers of alphago? What i do understand is that you quickly declare a program to be strong enough to play one of the 9 dan players. What i do understand from my own go program experiments...

Re: Don Dailey, 1956 -2013

Horrible way to die! Yeah he used to bring MiT students with him. Then stayed the weekend here. One occasion (not the year of the photo) i remember how the first day my mother had cooked a lot of different Dutch dishes. Don tasted everything. The 2 meter tall student hardly, as i had feared beforeha...

Re: Transposition table usage in quiescent search?

Hi, I was wondering whether the transposition (or hash) table should be used in the quiescent search, to cutoff already searched positions as well as to store the result. I see that Stockfish does it. I tried a simple implementation, just store all q-search results and returning the hash value if I...

Re: Transposition table usage in quiescent search?

A q-search entry in the hash table cannot generally be used to cause a cutoff in the non-qsearch part of the tree, because it has searched only a restricted subset of moves and so the score there is not valid in a part of the search that is not so restricted. Normally this is handled by giving q-se...
