It can't calculate cubeful equities using the database (except money game and a position in the two-sided database). I agree that for some match scores (like this one), there is no need to recurse mu
Hi Alain, Yeah you're right that cubeless equities can well be different for matchplay and money play. But not only is the equity different, also the 'Win' percentage is different that is shown toget
I spent a lot of time trying to understand what is meant by equity in the different dialog boxes and window panes. I read the Equities explained chapter in the technical notes section of
Well, that's exactly Misja's initial question: why the cubeless data for match is different from the one for money if they both come from the 2s bearoff db ? He was expecting to see the same figures.
Running GNUBG build 12/12/2002 on WinME. It appears from the output listed by GNUBG that it is not seeing the large 1-sided bearoff db, just the two in memory and the large version of the 2-sided db.
I'm afraid that won't work. You must name the file gnubg_os.bd and keep it in the same directory as gnubg.exe. If you haven't got room on your C: drive, you'd better re-install it on your large part
Okay, there are 5 different databases that GNUBG actually uses. As follows: gnubg_os0.bd The one sided bearoffdatabase (os=one sided) gnubg_ts0.bd The two sided bearoffdatabase (ts=two sided) hyper
I tried to move the 2-sided db out of the way, like you said. Just to confirm that I did it correctly: I went to the gnubg folder on my (unbuntu) pc and did 'mv gnubg_ts0.bd gnubg_ts0.bd_bak' Then I
I believe that the cubeless data are extracted from the 2-sided db as well. This results may well be different from that of an evaluation using the one-sided db. Try moving the 2-sided db out of the
Hi All, Thanks MaX for posting the question on this forum. So to Christian: You were saying that the cubeful bearoff db is used for moneygame but not for matches. But the differences that were spotte
Great job! Can't wait to see the full database when it's completed. Albert Hi all, I'm just a about to check in in my code for bearoff databases: * the one-sided 6pt database is now compiled into gnu
What databases did you download? (A URL would help). GNUBG comes with smaller Bearoff databases on most distros, and are automatically generated if you build from source. If I knew where you got your
Hi all, I've made a few changes to the generation of two sided bearoff databases. Instead of storing intermediate results in floating point numbers they're now stored as 2 byte integers. This has at
Arrrgh. I had a copy of the Windows version back when there was a problem where it was adding CR-LF's in my home directory. Gnubg uses database files in the current working directory in preference to

Hi all, on a forum I've found this: same position (in 2-sided bearoff dB) in money play and match play (3aw-3aw) shows different cubeless equities. I tried to explain it but I run into some confusion
These are the correct numbers taken from the two-sided bearoffdatabase. Yes, they are taken from the two-sided bearoffdatabase. 0.227 Note that gnubg will truncate the rollout at the bearoff databa
This position is *not* in the two-sided bearoffdatabase gnubg_ts0.bd. The two-sided bearoffdatabase covers 6 chequers on 6 points. Instead it's appears that there is something wrong with the one si
