Re: CCRL Engine Authors' Tournament (will start October 1st)

Chexa is pestering me to participate as well. Tried to stop her, but to no avail (she's sooo stubborn...) :-) Sergio should have the latest stable version. In case I manage to improve the dev version (squashing some bug my italian fellows know very well ;) ) I'll send it to Sergio before the end of ...

Re: Tool to recreate PGN from winboard.debug?

Maybe not exactly what you are asking for, but here you might find a tool that should convert to PGN the file that winboard creates with the /serverMoves parameter: http://www.g-sei.org/area-di-sviluppo/ Since he might not be able to read italian, let me address Sven and everybody might need this t...

Re: Creating Books from .PGN files

So a big problem is that when you get to the point where the samples are low, the statistics are just all noise. You don't want to mini-max that. Indeed. My plan goes further, actually: I want to make the engine gradually kick in as the stats get lower, so to avoid having the engine being brought u...

Re: Creating Books from .PGN files

To assign a score to a move in the book I use the expected score ( i.e. #wins+#draws/2 divided by #games) multiplied by the average number of "non-losses" (i.e. #wins+#draws divided by #games); the idea is that if a move leads to fewer draws is less reliable, possibly some refutation of the move is ...

Re: How do you count nodes?

Usually people put a time-control at the top of the search like: #define CONTROL 16383 search { if (nodes & CONTROL) { see if time reached..... } ... I have slightly different approach: I have a separate counter that I increase every time I increase node_count, then I do the ...

Somehow my router assigned new IP addresses to all computers in my LAN, so the external ports were all connected to the wrong computers! I had not noticed it.

It should work again now.
Hi HG,

this is just to notify to you that now I can connect.
Thanks a lot!

Re: On-line Blitz tourney June

Hi HGM,

since you are in the mood of fixing things :-)
Have you thought of a solution to the problem I mentioned to you lately, of some internet provider blocking the port one should use to connect to your ICS?

Re: Book learning

If pv nodes in the regular hash table are overwritten, then I suggest a separate pv node hash table that is permanent. There are only a few million important pv positions in total (for book usage anyway). Hadn't Ed Schroeder tried something along these lines in Rebel's heyday? I think it was called...
