Colossus 2026c now available

Post by MartinBryant »

I have just released an updated version of my Colossus Chess engine on my website at http://www.colossusgames.co.uk

This version is the first to use a NNUE. The network is a simple Chess768 architecture which was trained on 128 million quiet positions taken from self-play games using the Bullet trainer.
Hyper-bullet tests against the previous version indicate an improvement of slightly over 400 ELO.
I also ran a round-robin using the new and excellent Myracle GUI with a dozen engines in the relevant range.

Code: Select all

19800/19800 games, 27% draws, time control:8+0.08, book:openings-8ply-10k.pgn, event: ColossusChess2026c

Again this indicates a difference of slightly over 400 ELO. The Vajolet and Lynx engines are in the low 3300s on CCRL so I hope the new version of Colossus will achieve a similar rating at the longer time controls.

Nice! Congratulations with this milestone Maestro!

And Myracle is certainly a work of art.

This version is the first to use a NNUE. The network is a simple Chess768 architecture which was trained on 128 million quiet positions taken from self-play games using the Bullet trainer.
Hyper-bullet tests against the previous version indicate an improvement of slightly over 400 ELO.
I also ran a round-robin using the new and excellent Myracle GUI with a dozen engines in the relevant range.

Again this indicates a difference of slightly over 400 ELO. The Vajolet and Lynx engines are in the low 3300s on CCRL so I hope the new version of Colossus will achieve a similar rating at the longer time controls.
Congrats! I'll put it on the queue in FRC
