I'd like to correct a statement I made several months ago on this matter. It
then appeared to me (and I was certainly not one of the first to note it)
that 2-ply cube decision evaluations were better than those of 3-ply -
according to rollouts.
Now, at any rate with GNU 4/2009 version, on the basis of systematic
checking of very many positions (with the help of 0-ply-RO, 1-ply-RO,
2-world class-ply-RO and 2-supremo-ply-RO), I think otherwise: 2-ply cube
decision evalutaions are definitely better than 3-ply's in openning
positions and relatively simple middle-game positions. (3-ply is too
"daring" in declaring Doubles, Passes and Too Goods.) But as the game
prgresses or becomes more complicated, the tendency lessens and finally
turns around: 3-ply is superior particularly in positions where the side
trailing in the race nevertheless has the advantage; in those endings where
one side primes or closes out the other with most of the other's checkers
already borne out; and more types of complicated middle-game or endgame.
(There, 2-ply is too "caucious-conservative" in declaring Doubles, Passes
and Too Goods).
I should point out that a similar state of things seems to prevail (though
it was not as systematically checked) comparing in general odd-ply versus
even-ply cube decision evalutaions.

Hello all,

Re: Multi-core rollouts on Linux

If threads are supported (compiled in) you will be able to issue a

set threads 4

command. I don't believe much if anything has changed in this area
since august. You may also find help in Achim's rpms on acepoint.de,
but I'm not sure how up to date they are. You will probably need to
rebuild from srpm to get the to work on your fedora system.

Multi-core rollouts on Linux

2009-12-15T17:56:18Z

I've installed a version of gnubg from early August 2009 on a
multi-processor machine running Fedora 10, and the way I do long rollouts
is to type something like

gnubg -t < inputfile > outputfile &

This works fine, but I would like to take advantage of the multiple
processors to get the rollout to complete faster (or equivalently, to do a
longer rollout in the same amount of wall-clock time). Can I do so? How?

I vaguely recall some discussion a few months ago about some bug fixes.
It was a bit of a pain installing gnubg so I would like to avoid having to
reinstall if I can help it, but of course I will do so if necessary.

Thanks,
Tim

Thanks that's good to know. Explains why it worked on Lenny for me.

For the record, this turned out to be a bug in GTK+, which was fixed in
2.18.5.

Re: Two-Sided Bearoff DB and Cube Analysis

Yes, but I'm only seeking to apply cubeless winning chance to the pure
cubeless position that arises following D/T, when the winner of the game
wins the match.

Re: Two-Sided Bearoff DB and Cube Analysis

2009-12-12T05:30:11Z

The art of using cubeless winning chances in cubeful games is a gray
one at the best of times. The reason is that a) the plays may well
depend on the cube position and b) cubeactions leads to premature
ending of the games and c) the plied evaluation of the cube may
contain suboptimal plays because of the way that cubes and moves are
handled by the gnubg engine. So what seems simple is in fact not
because of the internals of the gnubg engine, which works fine in
general, but is quite puzzling to the human mind in positions we feel
we understand well.

I've never experienced gnubg hanging a pc on modern hardware. Anything
particular about you settings or pc, for example, the number of
threads or processor.

Gnubg priority

2009-12-11T06:52:49Z

Hi,

Is it possible to have the analysis and rollout threads of the program run with a lower priority than the rest of it? Or the whole software?
Because every time I analyse or rollout I have to set the process priority because if not it hangs the pc until it finishes.

Thank you very much,
Joaquin

Two-Sided Bearoff DB and Cube Analysis

2009-12-10T22:14:52Z

In the position below I received a cube which, if taken, is for the match. I have on disk the Two-Sided Bearoff DB for up to 11 chequers on 6 points, which gives:

Player Opponent
Position 4049 6690

Cubeless equity               : +0.5006
Owned cube                    : +0.7930
Centered cube                 : +0.7679

Opponent owns cube : +0.4452

It seems to me it is trivially easy to obtain from the Cubeless equity that, if the game is played out for the match, my opponent will win the match 75.03% of the time and my MWC is 24.97%. The rollout indeed concurs with these figures and, for once, 0-ply agrees as well.

As you increase the number of plys from 1-ply through to 7-ply, not only are all the figures wrong, but, there is a straightforward relatiosnhip of every ply higher being just as bad or worse than a ply lower. Analysis at 7-ply produces the worst result. Surely this is not what should be expected, and shouldn't all plys be bringing the correct figure here?

Thank you. That was the key that I needed. The problem is that
board_motion_notify is never being called in my build for a 3D board. It
is being called for the 2D board.

This should be set up properly by CreateGLWidget in board3d/widget3d.c.
Given that this is working for someone else in Debian stable, I suspect
some change in either the GTK+ libraries or (more likely given that I only
see a problem with the 3D board) in the GtkGlExt libraries, since that's
the distinction between the 3D board and the 2D board in terms of GTK+
event handling. Maybe somehow the OpenGL layer is getting in the way of
proper handling of motion events?

I'm using GtkGLExt 1.2.0 and GTK+ 2.18.4. What version are other people
who are not seeing this problem using?

Any ideas as to what could be going wrong here?

MouseMove3d() is called from board_drag() to handle drawing dragged pieces.

I'm increasingly suspicious that drawPieces not being called is the
explanation, mostly because I can't figure out what does call it while a
piece is being dragged. Where should I be looking for that to happen? I
see the restricted draws being called for the quick-draw case, but I don't
see any refreshing for the simpler non-quick-draw case. But maybe I'm
missing something obvious.

I tried to do more debugging, but I got lost in what calls what with the
3D board rendering. However, one additional, potentially useful piece of
information: I annotated board3d/drawboard3d.c:drawPieces thusly:

if (bd->DragTargetHelp)
{ /* highlight target points */
glPolygonMode(GL_FRONT, GL_LINE);
SetColour3d(0.f, 1.f, 0.f, 0.f); /* Nice bright green... */

/* =====> */ printf("Displaying target help points\n");
for (i = 0; i <= 3; i++)
{
int target = bd->iTargetHelpPoints[i];
if (target != -1)
{ /* Make sure texturing is disabled */
if (prd->ChequerMat[0].pTexture)
glDisable(GL_TEXTURE_2D);
drawPiece(bd3d->pieceList, bd3d, (unsigned int)target, Abs(bd->points[target]) + 1, TRUE);
}
}
glPolygonMode(GL_FRONT, GL_FILL);
}

and that printf statement is never called in my build. So something is
either failing to set DragTargetHelp or iTargetHelpPoints or drawPieces is
never called while a move is in progress. This seems to apply with either
quick-draw turned off or turned on.

I don't understand why I would be the only one seeing this, though.

Target help works fine with a 2D board.

I tried to use gdb to figure out why those variables aren't being set, but
it's very difficult to use gdb with gnubg and not have it lock up the X
server when one is trying to do it all on the same system.

strange result involving reported s.d. in very long rollout

2009-12-07T20:49:47Z

I rolled out 27aFAgDbtoUCAA:cAkgAAAAAAAA 1296^2 times at DMP
After 644721 rollouts it was at .610614 win chance and s.d. in win chance of .000015
After 1679616 (about 2.5 times as many games) it was at .610612 win chance and s.d in win chance
of .000020 How would the s.d. get so much larger when it should have gone down to about 5/8 of the .000015 value
to about .000008 or .000009

Is it a statisical fluke or is something going wrong?

I'm not sure if you are asking if you want to know how the positionID and
MatchID actually work (in the event you may also want to create your own
function, or use the existing ones). The Gnubg manual explains both here:

QuickDraw was off. I turned it on and saw the same thing. I did
double-check that the option to show the targets is on, and tried toggling
it to no effect. The computer player moves do show an animated checker,
and I think my moves show an animated checker when I finish the move
(although it's very fast), but the checker doesn't move when dragged and
there are no targets.

Attached is my config.h.

SSE2 is turned off since I'm doing a generic build for the Debian i386
architecture, which may run on systems without that support.

Re: Much reduced board decoration with 3D board

2009-12-06T20:04:49Z

I just did a cvs pull of head and:

./autogen.sh
./configure --enable-threads --emable-sse=sse2
make install

I ran it and in 3D I see bullseyes. It seems fine here.

If you go to Settings/Board Appearance and change QuickDraw on/off do you
see the same thing?

Yeah, I'm seeing it fine in 2D mode, but the bullseyes are missing in 3D.
I did go into the options/display tab and turned on all the animation (to
sliding), and it didn't make any difference.

Testing the display speed said that it was very fast.

I'm rebuilding outside a chroot now so that I can give you more details.
This is based on the most recent snapshot.

Should point out the bullseye (round) appear in 3d mode. In 2d mode when you
start dragging a green highlight/border is placed around the positions where
you can legally move to.

Re: Much reduced board decoration with 3D board

This is odd. I have roll my own build on Debian here (Debian Lenny Stable,
32 bit). I have animation on (You can select none/sliding/blink in
Settings/Options.../Display tab). When I attemot to drag a piece it jumps up
and then ilittle green bullseyes (crosshairs) appear on the spots where I
can make a valid move to. Seems you aren't getting those green indicators.
As well I seem to have animations (when they are turned on). Sounds like a
build problem and or a settings issue? Can you email me your config.h .

Much reduced board decoration with 3D board

2009-12-06T18:52:41Z

Hello folks,

I've been working today on updating the Debian gnubg package to the latest
snapshot, and I think I have everything mostly working. The one remaining
surprise (other than needing to sort out where Debian unstable hid the
Vera font) is that the 3D board seems to have significantly regressed from
the previous 0.90 version.

With the previous version, I could drag and drop checkers and the motion
of the checker would be animated. Now, the checker I'm dragging jumps up,
so that I know I'm moving it, but there's no other animation. Also, the
3D board used to have green line indicators showing valid moves, but those
now appear to be gone and the player has to know the correct moves. (As a
very casual player myself, the markings save me a little bit of time,
particularly when using all of a large dice roll.)

Are these intentional changes, or is there something wrong with my build?
And if there's something wrong with my build, any ideas what it might be?

HELP GNUBG ENGINE

2009-12-06T11:46:24Z

I'm trying to use the the gnubg engine with my own frontend what i
cant understand is how to use the position lib, ive organized my
BACKGAMMON TABLE in an array like int TABLE[28][2]; starting from the
first place where player gathers his checkers following the ace point
then 2th,3,4,5,,6,BAR,7..and so on until opponents gathering place and
the second dimension of table is used to hold the number of checkers
in each place and the colour of the checkers...How can i use the
position lib to transform this array to POSITION ID key or is there an
easier way to let gnubg know the current table? Thank you and sorry
for my bad english....

Menubar Widgets?

2009-12-05T06:02:45Z

I play in 3D almost exclusively in fullscreen with just the menubar showing.

It'd be great to get the option, ala Firefox, to use the very empty bar (widescreen monitor) to show useful data while keeping the screen clean. Pip count would be a classic example. Current match score. If in tutor mode let me see the numeric ranking for the move I'm about to accept, etc.

Also don't forget that those of us playing this way still have the bug of the doubling cube causing the board to resize down when the cube goes to the top even though it now doesn't extend outside the board borders.

Hi,

I have bought an a Apple Macbook Pro, running Mac OS X 10.6

Can you please let me know how I can install backgammon on this machine? (If you could point me to a step-by-step guide I'd appreciate it as I am an Apple novice).

Many thanks for any assistance.

Don't feel so bad. GnuBG is capable of crushing world-class human players and is insanely good at optimising its positions. I have been playing it for years, and only once have it beaten it in a 7-point match, something so rare, I tweeted about it (I consider myself to be merely a reasonable club standard).

If you want to learn, use it to analyse your play after the match. I learned a lot that way. I found the 6x6 temperature map especially enlightening.

If you want a more equal opponent, dial its intelligence down.

Richard.

Yes I stink but....

2009-12-04T13:12:43Z

First a "bug" and then the key thing:

I'm in Windows 7 x64 with the latest build and once every 7-game set
or so the game is hiccuping and the sound goes off causing the system
to run like a brick requiring a reboot. If I catch it right away (like
I'm not in a bar re-roll scenario) then I can just exit and all is
fine but if it goes on there's only the reboot. Also, once it happens
I can't save. No drive ever appears to save the file to.

Okay, some of you will know my name from chiming in once every 6
months with something minor over the last several years. I love this
product but I find it's become a love/hate relationship.

A little background:

1. I'm not a rocket scientist but the light does flicker pretty
solidly up there.

2. I owned a game testing company for 13 years and had to learn to
play every type of game--well, during that time.

3. I belong to a weekly board gaming club where we play "euro-style"
games pretty seriously and I win my fair share and this is at a top
college with rather bright students.

I say all that because GNUBG makes me feel like I should just go get
some sticks and figure out how to make a fire and kill animals with my
bare hands for food.

I play at the Advanced levels and (WARNING: I'm saying this from
frustration not logic) there are times I just feel like this damned
thing MUST be cheating even though I know it makes no sense for it to
do so. There has to be a psychology to it all.

I leave a pawn open in a critical time after being extremely careful
and, presto, far more often that seems possible he not only hits me
but rolls the perfect roll to do so. The only thing that can hit me?
5-4? He rolls a 5-4 I go on the bar and never recover. +50 lead shot
to hell in one open.
He also seems to roll doubles more often than I do while bearing off
especially if we're neck and neck.

It's gotten so bad that lately I've lost something like 10 sets (to 7)
in a row with most of them not even being anywhere near close. I've
also decided that UNDER NO CIRCUMSTANCES am I EVER to accept a double
from him. If he offers I decline and take the loss. Why? Because I can
only recall rare cases where accepting ever ended with my winning and,
seemingly often, as soon as I do it he rolls some amazing roll that
seals my fate right then and there.

I also started jotting down the PIP count after a minimal period of
five turns each. I did this for 25 games. After 25 games the total sum
of the values was -50. That's just -2 a game so that seems possible
but I'd feel a lot better if I didn't have the feeling that I'm always
on my way to a loss by that point already. I also play with Tutor on
and I'm not making lots of bad plays.

So my question has NOTHING to do with the engine. I KNOW it's not
cheating. Why am I having such a hard time with this? Must I accept
that backgammon just isn't my game? Is there some rosetta stone that
will help improve my game that I'm not aware of?

I've done a rollout of the top 8 candidate moves in a particular position
and have the SGF file. Now I want to save the result to HTML format.
When I do so, however, only the top 5 moves are exported. How do I get
all 8 moves to be exported?
