Information about the participants of the 3rd Lichess Bots Championship

Using an engine I wrote myself called Raven. Currently rated 1842 on the CCRL 40/4 though the version on lichess is slightly stronger since I've made a few updates since that version. Using an opening book but no endgame tablebases.

Hardware: AMD A9-9 Radeon R5, 5 Compute cores, 2C +3G 3.10GHz

Micah will join. Rating is somewhere around 2100 elo. It'll play on an old i7.

Fougade 3 Chess Engine, I'm developing in C language now. It contains %60 Cfish's source codes. But I'm working on this, I'm gonna do it all of codes myself. Fougade plays +3100 elo on Intel Core i7 and GT 550 graphic card.

This BOT is powered by a C++ engine called 'Googleplex Starthinker'.
This is the sixth engine I've written. Currently, I am working on a tuning method for evaluation parameters and I hope it will be ready for the tournament :)
It's listed in the CCRL rating lists at ~2300.

Normally the engine runs on the smallest Google Cloud instance you can get (because it's free ;) on a Haswell Xeon @ 2.30GHz with 0.5GB memory. However, since it gets throttled if I use it too much, I'll try to find a better machine for the tournament.

Here on lichess the BOT plays standard chess in every time control except correspondence and hyperbullet.

Whole lotta Stockfish in this tournament ...

This bot learns to play better chess by mimicking biological evolution: two randomly mutated copies of the bot play a game, the winner reproduces and the loser dies. The process usually takes a day to get better than its author (which isn't saying much).

Runs on a decade-old desktop, written in C++.

Hardware: AMD FX-8350, 8 cores
Engine and settings: Stockfish 10 (stockfish_10_x64_modern), 8 threads, Pondering enabled
