This NN version is Komodo MCTS with a little help from NN.
what you mean with little help? perhaps the regular evaluation is still used together with the NN one?
It uses output from both normal Komodo MCTS searching and NN. How it combines them is proprietary.

Re: A Gilden rematch

Right now the focus is on how to best combine Komodo with any existing NN, rather than making our own NN. Once we have found a sufficiently good way to do that, we will likely turn our attention to the NN itself. But for the way we are using the NN now, it wouldn't be a sensible use of resources to...

Re: AlphaZero No Castling Chess

I will try to build now a reasonable book (EPD suite) with Lc0. It doesn't have Contempt, though. With this trapezoidal noise for Lc0, limiting the bad moves to no more than 2% offset from the best move (win probability) { "name" : "Temperature", "value" : "0.60" }, { "name" : "TempDecayMoves", "va...

Re: In No castling Chess what Engine would be the King or the best?

This is quite balanced according SF and Komodo. Position is in equilibrium state of matter. It appears that disabling short castling, somehow equalize the first move advantage. White can castle on the queenside whereas black can castle either side FRC style. rnbkqbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQK...

Re: In No castling Chess what Engine would be the King or the best?

What about w/o castling for white here and normal castling for black (FRC style) rnbkqbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1 Well, if Black can castle either side and White can't castle at all, that should favor Black clearly. It's not obvious what the reversal of K and Q favors one si...

Re: In No castling Chess what Engine would be the King or the best?

What about testing this "double" fischer random position. Since white moves first, white king squares are swapped to even out the first move advantage. rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBKQBNR w KQkq - 0 1 Are you assuming normal chess castling (so White can't castle here) or FRC castling rules?...

Re: AlphaZero No Castling Chess

I ran the following test last night. Komodo 13.2.5 (regular mode) vs K2453.00 MCTS (latest dev), with regular K on one thread and MCTS on2, to make them realsonably competitive (regular won by 39 elo). 2 min + 1", White Contempt 75 (maybe I need to rerun it with Contempt 50 in view of your results)...

Re: A Gilden rematch

The announcement Komodo NN can be something similar to a christmas gift from team Komodo. Maybe opt for GPU donation for Komodo NN improvement. Stockfish and Leela relies on voluntary CPU / GPU donation. Maybe this is something to consider. Right now the focus is on how to best combine Komodo with ...

Second, Lc0 testing, between best t40 and t30 nets: 2000 games at 100 nodes/move: +1064 =386 -550 62.8% White score: 53.2% 1000 games at 1000 nodes/move +514 =303 -183 66.5% White score: 51.4% Draw rate increases to longer TC, Armageddon score decreases from above towards 50%. Again, a promising re...
