New engine releases 2020

[silentshark]

I have released Francesca 0.30. Available from www.silentshark.co.uk

Not a huge jump in strength, maybe 30 ELO or so.

Changes

Small changes. Minor optimisations. More aggressive null move pruning. IID replaced by IIR (thanks to Ed Schroder for idea). Tweak to futility to make more aggressive or not, depending on if position is improving. Separate search functions when in check. Minor eval tweaks - tuning needed

Happy Christmas to everyone. Let's hope 2021 is a better year, and the world gets on top of the Coronavirus.

Thanks Tom and the best wishes.

Thanks, Gabor, and same to you

Thank you for the release of the Happy New Year engine, Günther. Let me add my own best wishes to the community.

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

For any questions related to this release please post them at official Igel thread http://talkchess.com/forum3/viewtopic.p ... 26#p877326

Great news. I will test Igel 2.9, when the testrun of Stockfish 201225 is finished (tomorrow, hopefully).

That's nice, but if I am not mistaken it is a GUI with internal chess engine, which cannot be played in/with other GUIs.
BTW it seems to have the lichess.api integrated - this is also a fine feature.
