Indeed, it would be premature to drop 32 bit support. There is a huge (and growing) Android market and all Android devices are 32bit only.

Just to be clear, did you take statistics only when the move was a NEW move and not the same move from the previous iteration?
Yes, only when the move was a different one.

Re: Komodo bug?

I did some research with Critter about handling fail highs at root. I measured the probability of unresolved fail highs being the new best move. Whenever the time management decided to stop the search and there was an unresolved fail high, I forced the engine to finish the iteration and logged the ...

Re: Open letter to chess programmers

I guess what would be the percentage of coincidence if we execute the fingerprint N times with the same engine. Can this test give us a (somehow) error margin? Has anyone tried this test? with ~8,000 positions, an error of ~ 0.5% 1 standard deviation, if I remember well. I think that the SD is even...

Re: Weekend entertainment with the IPON

After 985 games: Perf=3026.

Based on this preliminary rating, I would say that Ingo hacked my computer and this is a development snapshot of Critter :)

Re: Continuation of Critter would be very appreciated

Is Critter discontinued?! I regularly check http://www.vlasak.biz/critter/ but for almost a year, no update. I consider this engine to be among the very top, with very good features like session file (= permanent learning), and Gaviota access. Great strong engine. IIRC, Richard warned last year he ...

Re: Opening files in windows 7&8

Hello, After I upgraded my development machine and test machine to windows 7 and 8, my programs open a window (cancel, retry or ignore) when a file or disk is not found: FILE *fOut = fopen(....... if (fOut == NULL) { .... } It looks that Windows pops up the retry windows before the 'if' command, an...

Re: Extracting info from Critter session file

Are there GUIs that support this format? No. Or must people that want to use the session file always run Critter from the command line? If they want to manually override/delete individual entries then yes. Otherwise it is fully transparent to the user. If the latter is the case, would you have any ...
