Re: The public IPON is finished.

There is nothing like releasing a new version of your engine to make you miss IPON. Watching the live updates was always fun.

Re: Hannibal 1.4 released

We expected to reached Hannibal in 5 years, now it is going to be 6!! :-) Miguel PS: Good job guys, I know that SMP stuff is tricky. So getting improvement there must be very satisfying. The SMP improvement is pretty much all Edsel's work, which makes it doubly satisfying for me :). We will try to ...

Re: Hannibal 1.4 released

Hi Edsel and Sam, Am I correct in assuming this version will get more of a boost when using multiple cores? Please say no. Gaviota is trying to catch up to Hannibal :) Keep up the good work guys! Sorry. While the elo gain will be modest with a single core, with multiple cores I expect it will be su...

Re: Hannibal 1.4 released

Cool stuff. However, I can't seem to get either the 32 bit or 64 bit compile to work with a Polyglot book. I did select the OwnBook UCI option. We'll be looking into it and upload an update if it is necessary. Its necessary. We will probably release a patched version tomorrow, which will have no fu...

Re: Tuning for rating lists ?

There is this magical parameter, called "contempt" that has this interesting property, if enabled lets your engine to become strong with the weakest and weak with the strongest yes, is not a very ethical one :-) Apart from the technical merit of this: I have serious doubts that just tweaking the dr...

Re: Stockfish 4

The CCRL and CEGT lack precision due to the use of different computers, which means the difference between popcount and non-popcount can be blurred. IPON is more precise, though it probably is a less accurate indicator of an engine's relative strength on a random computer. As Ingo indicated yesterd...

Re: huge opening file like 8moves_GM.pgn?

Hi Sam, This should be the link to where I uploaded the 8moves_GM file: http://www.mediafire.com/?qb8bt8k9acdq1ko I think that the Stockfish testers have found a few dubious openings that slipped through my filtering, but it seems to be okay overall. One improvement would be removing the openings t...

huge opening file like 8moves_GM.pgn?

Hi,

Is there somewhere I can download a file with a lot of starting positions for computer chess testing? I got the impression stockfish was using 8moves_GM.pgn but I have failed to find a copy of it (or something similar).

Re: Castling long

There is always the possibility that Alekhine and Kasparov castled long more frequently than others not because they thought it was objectively best, but because the resulting positions were more unbalanced (more likely to lead to a decisive result for one side or the other). -Sam By the level of A...
