Another bug: "follow" does not show the game if the account you want to follow is presently playing a game.

Thanks for notifying me, I will look at it. The Lasker software is filled with bugs.

Re: On-line engine blitz tourney October

There was an issue with sendmail tranferring messages to the external relay, it was difficult to find out what causes this, I finally switched to ssmtp, 'mailoldmoves' and 'mailstored' should be working now. At the moment we have about 23 registered accounts, on Harm Geert's server there used to be ...

Re: On-line engine blitz tourney October

The server works but seems to be missing a few little things. "rematch" command is not recognized. "eco" command does not work while observing, only if playing or examining. These are nothing major, though. The server is based on the public domain Lasker/Capablanca code, some commands and variables...

Re: On-line engine blitz tourney October

Some remarks: Initial ratings are set at 2500, nowadays an average engine has at least 2500 Elo. It might be good to play some games before the start of the tournament to get the initial ratings a bit more accurate. Channel 1 is the help channel, channel 64 is the computer-chess channel and channel ...

Re: On-line engine blitz tourney October

The proposal is to have the tournament take place on saturday October 12th at 20:00 CET (14:00 EDT), so that is 1 hour earlier than before!!! If this is inconvenient for some people we can always reconsider. Lisebeth (an experienced TD from ICC) will be our TD. You can reach the server at 'nightmare...

Re: kiwipete perft position

Hi hi hi my class ChessPiece still exists but only containing constants and static methods now. Took three years to get there. Can you imagine how many bugs and time I would have saved when I would have taken the right design decision from start. So for beginners who do object oriented programming:...

Re: On-line engine blitz tourney July

Just found another bug in pending.c, procedure add_pending at line 84. The new pending struct is not fully initialized, new->status contained garbage en is used later on without properly initializing it. This caused some weird behavior when matching other players. My guess is that there a lot more o...

Re: Search speed

Krzyzstof probably means n/s speed, lowering the branching factor increases search depth but not search speed. Lowering the branching factor helps to make the engine tactically stronger, engines with a very low branching factor play a silly kind of chess, they don't give much (if anything) away, the...

Re: Google's secret computer?

For the fastest machines around, the top two are at Oak Ridge Lab and Lawrence Livermore Labs. The NEXT two are in China... That is when you count flops, the top two use a bunch of NVidia GV100 racks, maybe nice for a NN engine. The new Chinese Tianhe-3 will be operational next year and is going to...
