Re: Koivisto 6.0

Congratulations on the new release and huge progress! Furthermore we introduced a completely new time-management scheme which, as far as we know, has never been tested in any other engine. We use the internal node counts for subtrees to check how many good moves at the root there are and based on th...

Re: Winter

I don't want to spam forum with every little patch, but version 0.9.5 adds support for Fischer Random / Chess960, which feels like a feature some people care about. Winter's implementation should actually support positions with vertically asymmetric castling. So you could expand the starting positio...

Re: Learning search algorithms using neural networks

A group of researchers have trained recurrent neural networks to learn how to perform a number of algorithms, including Monte-Carlo tree search for chess which is used in a number of engines such as Dragon, Leela, and Shashchess (Stockfish derivative), without handcrafting the search algorithm itse...

Re: Winter

I don't want to say too much, but I have been getting a lot more motivated to work on computer chess again :) I finally got around to testing a pull request made back in March (thanks again to Anurag Singh) which added support for Android. Support relies on an open source header file which I removed...

Re: Computers are now superior to humans in turn-based strategy games

There is one game, that I am not certain of an approach which would lead to an engine strong enough to beat me. I have some ideas, but hard to say if they are enough to beat strong human chess players that have played the variant for a while. I am referring to the fog of war variant on chess.com. I ...

Re: Winter is Coming (Amoeba, Beef, Combusk, Demoli, Fab, Halogen, Koivi, Lc0, Marvin, Minic, Nemori, Orion, Pedone, Win

Thank you for the tournament! Indeed luck for sure plays a big part in 58 rounds. From the rating lists we know the two Winters are closer to about 100 Elo separation whereas here the performance differs by about 170. I quite enjoyed following the classic old-school large double round robin format. ...

Re: Chess programs :: Source available, but not today?

This is an interesting problem. My intuition would be that if they are open source it should be fine to rehost them. That being said if the source is deliberately being taken down by the program author (eg because they don't want to have a github account), the ethical situation is less clear. For th...

Thank you for testing!

I usually had the games open in the background and followed a decent few interesting ones :)

Re: Winter is Coming (Amoeba, Beef, Combusk, Demoli, Fab, Halogen, Koivi, Lc0, Marvin, Minic, Nemori, Orion, Pedone, Win

That was a fantastic game! Perhaps a bit too adventurous by Winter indeed, but also well defended by Fab.

Thanks for including Winter in your tournament!
