Hjalmar Munsterhjelm - Koivikko ja ruispelto [1]
Koivisto,
an UCI compliant open source chess engine by Finn Eggers and Kim Kåhre, written in C++, and first released on GitHub in September 2020 under the GPL v3.0. The bitboard engine provides automated evaluation tuning by logistic regression, either using stochastic gradient descent or AdaGrad. However, the current perceptron approach of the evaluation may soon be replaced by an own NNUE [2] [3].

The download link is not working, because I have changed it!
I dislike direct linking to plain files on my site.
There is a structured download site, which has several infos for all downloads!
People have to respect this. I do this for free and there is no ad-aware nor spam nor clickshit.

Here is the new results of koivisto 8 against other top engines in the latest ccrl 40/15 rating list. I think in 1 or2 next updates it can easily compete with latest stockfish and its derivatives. Great work by Koivisto team.
