Re: New engine releases

Winter 0.3 has been released. I wanted to wait and make a binary as well for Android, but I have realized I have been using that as an excuse not to release it for the passed 10 days or so and since I told myself I wouldn't test any new ideas until after I released a new version... Well, I add Andro...

Re: Alphazero news

Hi Matthew, Nice to see you on the forum again! I was a big fan of your probability based search. In fact, shortly after you published your thesis I read it and my only confusion was why you did it in chess and not Go, so I wrote my B.Sc. thesis doing exactly that. Naturally, I was wondering whethe...

Re: LCZero GPU memory requirements?

As a disclaimer, I am not actually all too familiar with the Leela codebase. That being said I don't think it should be an issue. First of all, keep in mind people are using neural nets with much larger images than chess boards. If you have an image which is 1024x1024 (around half of "full HD") than...

Re: Eight-Headed Monsters X 8CPU

No graphics card for Lc0/DeusX ? No graphics card, as this computer was originally built with only chess in mind. Looked at the Round 1 results : Lc0 and DeusX have disappeared. So I was right, it was a joke to include them... (?) Maybe I am reading this wrong, but I think Graham deserves more resp...

Re: Open Swiss Edition II

Even by Winter's standards, that was a crazy game. Looks very Tal-like to me =) Some games of Round 6: [Event "Open Swiss Ed.II"] [Site "?"] [Date "2018.11.30"] [Round "6.11"] [White "Winter 0.2 64-bit"] [Black "CT800 1.32 64-bit"] [Result "1-0"] [ECO "E05"] [TimeControl "40/840:40/840:40/840"] [Ply...

Re: Lazy SMP and 44 cores

There are a few things which I could imagine makes Lazy SMP less effective in Winter. Eg There are no reductions at the root node and Winter does not use the history heuristic in any way at the moment, so the search is less stochastic. The scheme I ended up coming up with was to use the one describe...

Re: What is the highest piece odd that Komodo or Stockfish can give the top 4 GMs

Hard to say what the largest handicap is. There was a recent rapid handicap match between Komodo MCTS and MVL which included handicaps such as 2 pawns, exchange + pawn and knight g1 for pawn f7. Komodo won the match with 4.5 - 1.5 (I am ignoring the non-handicap games where they set Komodo to weaker...

Re: On-line engine blitz tourney September

Is it no longer a thing to post your engines games after the tournament? Somewhat unsurprisingly this turned out to be Winters best tournament yet. I am very happy with how it performed and hope I will be able to keep the trend going for a while =) Easily Winters best game was its win against Singul...

Re: Rising Stars v Fading Warriors II Teams Match

I went through Winters games and thought some of you might enjoy Winters last win as much as I do. Winters first move of the game was a positional pawn sacrifice and two more followed. At no point in the game after the third pawn sac did black think it was any worse while white was convinced of a +2...

Re: The Booot Mob v Godel's Grinders

I am a bit confused why Winter - CM11 was adjudicated a draw in game 4? I believe it would have ended in a draw had they played on, the result is fine, but it seems to me a bit of an arbitrary point in time for an adjudication (both engines preferred white and a pawn was pushed during the passed 10 ...
