Koivisto 8.0

Post by Luecx »

Fellow chess enthusiasts,
It's been a while since we released v7.0, but now it's finally time for another release. Koivisto has improved in all areas since (search, time managment, and evaluation), and is now so much stronger that we just couldn't justify delaying the release further.

Code: Select all

ELO   | 151.93 +- 3.24 (95%) 
CONF  | 8.0+0.08s Threads=1 Hash=8MB 
GAMES | N: 20000 W: 8925 L: 697 D: 10378
Feautering with this release, we created a website for Koivisto which even allows you to play Koivisto in your browser (this is experimental for now): https://koivisto-chess.com/. It contains informations about the engine, the history and the people working on this project. Furthermore you can download the latest released version, which should be Koivisto 8.0 from the website as well as from out github release page. If you find any bugs within the website, feel free to let us know :)

Coming with Koivisto 8.0, we reworked the neural network architecture various times. We came up with an input mapping which will hopefully be able to distinguish between crucial king positions and also avoid overfitting on the restricted dataset from Koivisto self-play games we use for training. Our training pipeline has been reworked and has been ported to CUDA. The project for the Tuner is publicly available. A detailed explanation on our solution can be found on our wiki https://github.com/Luecx/Koivisto/wiki.

A special thanks goes to the open source chess engine community, especially the OpenBench community. Discussions with other members of the OpenBunch have been invaluable for the development of Koivisto. One case worth mention is threat history, a great idea by Connor first implemented in his engine Seer. This was based on the Koi definition of threats, but combining it with history. Connor's Idea then made it back to Koivisto, gaining ~5 elo. The general interaction with other wonderful engine developers has gained us much more.

We believe engines being open source is essential for sharing ideas & progress. The impact of Stockfish can hardly be overstated, but we believe weaker engines have a lot to contribute too. Progress in computer chess has been a collective effort, and we believe that's something we should cherish.

Finny & Kimmy.

90% of coding is debugging, the other 10% is writing bugs.

I have been using this format that does both vertical-symmetry and the 16 king square buckets you use in almost the same way for quite some time.
My network "net-scorpio-k16" is named for that. Here is the link where I explained my approach:

It is a funny coincidence. I was not aware of this but we discussed this in the TCEC chat. I added the fact that we developed it independently on our github wiki.
