Clover - UCI chess engine
Author: Luca Metehau Rating CEDR=3159
v.6.0:
New release is here! Progress is slowing down a bit and it will continue to do so, as uni time is coming soon :).
Nevertheless, Elo gains are decent in standard chess, 35-40 self-play Elo, which hopefully translates nice vs other engines.
In (D)FRC, gains are massive, around 145-150 Elo!!
Aaaand, as requested, Clover now supports Ponder! :) Although, I am 95% sure it works, I'd rather get some external feedback on it ;)
Some notes about changes:
New network arch with 1024x2 neurons for L2, trained on DFRC data, which is the main reason the DFRC gains are so massive.
Various search changes and some cleanups
That's it for now, have fun trying Clover and report any bugs! ;)
