Re: Chess Fighter Neural Net

I have had a similar frustrating experience with reinforcement learning before i deemed it too big a project for one man. What input planes do you use besides piece placement?

Re: Allie & Stein

Guenther, almost certainly the problem you are seeing is because of a mismatch between the cuda libraries I built with and the ones you have installed. I built the binary with cuda 10.0. You can look at the appveyor.yml script which has the exact cuda files to download and install. Tried several co...

Re: Allie & Stein

The cuda dlls are delivered with each LC0 download since several months at least. He will also need the appropriate qt5core.dll. But all of this is invain anyway, because he has no available cuda hardware (can be deducted from earlier posts of him). It depends. It used to be that one had to go thro...

I am unfamiliar with QT, I get this error when I try it on Windows. A link is appreciated if someone has got it. https://i.imgur.com/idvSpOi.png I have been making an appveyor.yml script for building on windows, but it still doesn't quite work for reasons I don't understand. If I do roughly the sam...

Re: Training the trainer: how is it done for Stockfish?

On why AlphaZero (and hence LC0) opted for a Monte Carlo search... There are no strong chess engines which use alpha-beta pruning alone. All the strong engines use other techniques to do a huge amount of pruning. These other techniques are mostly chess-specific, so no good for DeepMind's purposes. ...

Re: Training the trainer: how is it done for Stockfish?

Regarding: "Very simple. MCTS is the only viable approach given the 80000 nps they got using 4 TPUs." Well, A/B fully replaced any other scheme when computers where much slower than 80Knps, and MCTS never won above A/B in any period of chess engine history...so maybe not so simple :-) Regrading: "i...
