Re: How good is the RTX 2080 Ti for Leela?

How does that compare to a 1080 or 1080 ti?

Re: How good is the RTX 2080 Ti for Leela?

Nobody has one, so nobody knows. According to Milos, it's only going to gain from the clock speed, so maybe 10%-15% faster. We'll know for sure once they are actually in the market.

Re: Monte Carlo or Minimax?

Stockfish first release was in 2008. So the version that Alpha Zero played against had been in development for 9 years. More, if you count the development time of its immediate predecessor, Glaurung. It was far, far down the alphabeta path before it was shown that monte carlo methods were a viable a...

Re: Monte Carlo or Minimax?

Hi, I'm new to this forum and pondering about making a chess engine in the future, maybe. Which algoritm is best suited for this task, both practically and theoretically: Monte Carlo or Minimax? If former, why everybody is implementing Minimax? It latter, how come AlphaZero did such an impressive j...

Re: leela is official(?) better than sf9

I think "the latest version of Leela" is probably an oxymoron. :)

I'll be happy to verify, but could we perhaps use something slightly more modern than MD5, now that we're in 2018? =) SHA-256, perhaps?
Forgive my ignorance, but why would you prefer one over the other?

Re: Texel tuning speed

In the training set not every position has to be unique and different from each other, a position that can be won in game A can be drawn or lost in game B, and this all averages out in the error function. When you train with unique positions only you have no statistical info whatsoever. I think eve...

Re: Learning time growing exponentially with number of training examples

The problem with Leela was that they were training with bugged versions, recently they found another bug in the 50 move draw recognition. I never understood all these restarts from scratch, a network can also unlearn wrong information. Bugs were just one of many issues to address. The AlphaZero pap...
