Re: Training positions from gm2600 pgn

Hello Vladimir, Amazing! Let me know if you need some help in testing or the training for GreKo. I am renting 32 threads AMD EPYC hardware for Igel training/dev work, so I can always spare resources for Igel's father :) Thank you for this kind offering! Currently I rebuild evaluation, trying to fig...

Re: Training positions from gm2600 pgn

Vladimir, I was wondering for quite a bit of time regarding this non-related question - Igel chess engine It's author said that it's a GreKo's derivative. It seems like Igel is 600+ Elo points stronger. I can't see another way to get 600+ Elo points other that copypaste stockfish NNUE, but I guess ...

Re: Training positions from gm2600 pgn

How long does it take to evaluate million of positions in GreKo's errSq() routine? (mean square error calculator) Below is output of learning on file with 1 million positions: GreKo 210108 (08-Jan-2021) White(1): learn CCRL_1000_K Algorithm: stochastic gradient descent Parameters: 204 Initial value...

Re: Training positions from gm2600 pgn

P.S. Your "learn" feature in GreKo is awesome. Thank you! I plan to release soon a new version with better learning capabilities. For example, coordinate descent is replaced with stochastic gradient descent, which is orders of magnitude faster. Also some sort of TD-learning after each game is imple...

Re: Training positions from gm2600 pgn

In my experiments with Texel tuning datasets generated from gm2600.pgn usually perform worse than from CCRL games, for subsets of equal size.
Also, I usually skip positions in check, after captures and promotions, and randomly select one position per game, to decrease correlations between samples.

Re: MacHack under PDP-10 emulation (HOWTO)

P.S. One match I am curious about: Ken Thompson included his simple chess program in early Unix distributions. I wonder which was stronger?) Sorry for off-topic question. I remember a chess program which was included as a code example in Borland C++ package in early 90's. It had own GUI and could r...

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

Sorry for off-topic, but could anybody give me a link to lc0 network (weights file) which played in TCEC-15 Superfinal? As I know it is not a regular net available from the official lc0 site.

Re: LC0 For Android!!! History Made!!

It would be really nice to have something like go playing Leela: https://play.google.com/store/apps/deta ... android.aq
When you install application from the Market and it just works - all work with weights being handled in internal dialogs/settings of the program.

I hope in a year or two, Igel will beat Stockfish on the same time control and the same hardware :-) Currently in all my tests the elo difference between them is infinity.
Stockfish is obsolete, lc0 seems to be a more worthy goal :)
