Re: On-line engine blitz tourney October

I've put the server on a Hyper-V virtual machine on a machine with a core i5-9400 processor (a really fast processor, draws hardly any power when idle). Last time the performance was already good, next time it will be even better. There are still some bugs and omissions in the server software, maybe...

December 7/8, the 56th Programmer Tournament and 39th User Tournament will be held.
This coincides with the ACTA tournament from Charles Roberson, maybe not so handy!

Re: Ataxx

Re: Ataxx

It is a piece of cake to change my old Othello/Reversi program in such a way that it can play Ataxx. I don't know how difficult it is to let the Chess-server I just put up recognize something like Ataxx. HG is the only one with experience in adding variants to the server.

Re: kiwipete perft position

I have a strange scheme, I use the piece values as index into the bitboard arrays. I use the following constants: White = 0; Black = 1; Empty = 0; Pawn = 1; Knight = 2; Bishop = 3; Rook = 4; Queen = 5; King = 6; const white_pawn = White | Pawn << 1; const black_pawn = Black | Pawn << 1; etc. PieceTy...

Re: On-line engine blitz tourney October

Sure, but I'm not reading everybody's finger-notes. My expectation was that somebody joining the tournament with an engine is the original author of that engine, with maybe a few exceptions there.

Re: On-line engine blitz tourney October

Thanks for the info Joost, though Phalanx and Eichhoernchen have different authors. This is very strange because Belfish, Eichhoernchen and Phalanx were registered by the same person. According to CPW there were several different people working on Phalanx in the past. The last person working active...

Re: On-line engine blitz tourney October

Belfish is from the same author as Phalanx and Eichhoernchen.

His finger notes say:

1: StockFish derivative
2: experimenting with evaluation function, with small techniques for speeding up code execution, with compiling options ...
3: running commonly unattended
