Re: Introducing Igel chess engine
The official Igel executable are at https://github.com/vshcherbyna/igel/releases/tag/2.9.0
The binaries I compile for people are custom and best suited for their cpu architecture (in terms of performance), so it is not a general purpose releases, hence I will not publish them on the project page.

+85 Elo points (after only 13 games) in my test vs. SlowChess Blitz Classic 2.4 x64 (TC=4'+2").voffka wrote: ↑Fri Dec 25, 2020 9:44 pm
Igel 2.9.0 at https://github.com/vshcherbyna/igel/releases/tag/2.9.0 (official executable binaries for Windows and IGN net).
After three months of generating data using Igel's own search and evaluation and training several network architectures I am happy to announce a new version of Igel 2.9.0 that uses it's own network trained on Igel search/eval data (around 2.3 billions of depth 8 and 500 millions of depth 12). Earlier versions of this network seen strong participation of Igel in TCEC Season 20 and should bring more than 20 elo of strength at LTC.
What's new:
- Switch to own network based on Igel search and evaluation (ign-0-9b1937cc)
- NNUE dynamic eval scaling
Regression run against Igel 2.8.0 at 60s+0.6:
Code: Select all
ELO | 24.06 +- 5.30 (95%) SPRT | 60.0+0.6s Threads=1 Hash=64MB LLR | 0.00 (-2.94, 2.94) [0.00, 0.00] Games | N: 7376 W: 1908 L: 1398 D: 4070

Re: Introducing Igel chess engine
Your sample size is too small You will need to run around 16k long time control games to get something precise, here is the run from updated regression:

Re: Introducing Igel chess engine
1.-I know. In fact is just the overture of my test (100 games at TC=4'+2" - 12-15 minutes per game);
2.-
3.- This is a job for CCRL, CEGT & co. My tests are just orientative. Nothing more.

Hi Volodymyr !
Thanks for the new release !
Please could you provide a windows binary of Igel 2.9.0 designed for Sandy Bridge or for westemere architecture that supports only SSE4.1, SSE4.2 and POPCNT.

Thank you
Greetings,
Jamal
