"Clovis is born again!"
With these words, Mr. Jonathan McDermid announces the release of the latest version of his chess engine.
Clovis is a free open source chess engine under the MIT license.
Here are the changes that have taken place in the latest version of Clovis III.
implemented gradient descent tuner
disabled drawishness and some other evaluation functions until they are integrated into tuner
added some params to evaluation (candidate passer, rook on seventh)
vertically mirrored some PSQTs
Certainly, Clovis III is stronger than its predecessors. Considering that Clovis uses HCE (hand craft eval) and it has only been a little over 1 month since the release of the Clovis I, the 133 Elo difference between Clovis I and Clovis III is not small number.

This shows that the author is making an effort and working on his engine!
I think it is worth paying attention to Clovis - an engine that, in my opinion, has great potential. Currently, Clovis does not use a neural network and already plays strong chess. I predict that if in the future Mr. Jonathan McDermid decides to develop Clovis with the possibility of using a neural network, we can look forward to a really strong computer player.
I encourage you to download and use this interesting and regularly developed chess engine.
