Clovis III - released.

"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.
