I bought Robertie's new book and so got onto his mailing list.Yes. The game maker claims that he used AI to improve, but that is total bull. It now cheats like crazy.
One thing he mentioned recently is that the Tesla backgammon
program has apparently improved from being a terrible player
to being a challenging player. Does anyone here know anything
about this?
From a business point of view, it would seem much better to
have a weak program than a strong program, since you want to
make the customer feel smart.

20 Million games is enough for a quite decent player......Yes, I was rather surprised when I first learned that 20 million games was enough training data for a decent bot, because I was naively guessing that it would require ten times as much as that. But apparently, even AlphaZero chess used only 44 million chess games, so these neural nets are somehow able to generalize incredibly well from (what seems to me like) relatively little data.
if you know what you do. Maybe they should ask one who knows what to do ;)
But as Tim pointed out: for the average customer to keep happy playing strength might not the right way to go. Does one remember the "Big Bang Board Games" Apple put on their Macs a decade or so ago. Much Bling-Bling and abysmal game play....I have posted here before about the terrible level of play of the backgammon game on JetBlue. But Stick has a point...if the computer player is *too* weak then that can also be unappealing.
FWIW, my intuition was also that the low tens of millions would be far too few for
complex games like chess or backgammon.
I think that now, there's a strong consensus that both XG and Gnu are much stronger than any human,
and I'm sure there are plenty of other bots that surpass human play.

As in an earlier post:
- XG
- GnuBG
- BGBlitz
- Snowie
are very very probably better than any human on average
TD-Gammon/Jellyfish/Motif? Are you sure that these are better than *any* human. If Mochy, ZZ and Ueda play together as a team against them, on whom you would bet? I'm *very* unsure
Do I miss some other?
Motif was terrible last time I played it. It may have improved since then....
I wanted to test the latest Motif but I was stuck on the Java requirements. I got this message: "If this message appears, then your web browser does not run Java and you will not be able to play Motif backgammon."Java in the browser isn't supported in Browsers nowadays (for good reasons but this is a long long story)

I checked when Java was thrown out of java itself, but it was in Java 9 so your Java 1.8 should work. The program would be the "appletviewer"... but it don't
so before investing a lot of time I thought: let's try it with an old environment, but on my recent boxes no browser supports the Java-plugin and on the older (OS/2 in a VM, iMac from 2000) they couldn't handle the new algos for https/ssl :(
finally I checked it with curl whether the files are still there.... and they are. I downloaded them and packed them together at.
https://bgblitz.com/download/misc/Motif.zip
If you
- download it,
- unpack it at any convenient place
- cd the commandline in this directory
- and call
appletviewer ./motif.html
it should work (at least on a Linux and a Mac it works. To lazy to start WIndows).
BTW there is a webpage , where Hans-Jürgen Schäfer collects elo numbers from every BG bot he can get:
https://mustrum.de/blot.html
It is in German, but if you scroll down you'll find the elo numbers. I don't know his exact procedure, but the number looks plausible to me. The most bias is probably due to setting max elo to 2050.
Astonishing/amazing how bad some bots are....

If I remember rightly, it was an open question
whether TD-Gammon was better/worse/equal
when compared to the world's strongest humans.

both XG and Gnu are much stronger than any human

Nobody other than yourself does hardly everNot that I believe that you were reachable for arguments or facts, but feel free to make some matches with BGBlitz (I suggest 4- or 5-ply) or BGBlitz against itself and feed them to XG. You don't regard PR as reasonable IIRC but Snowie is a bit over 1
mention, let alone praise, your garbage bot

IIRC but Snowie is a bit over 1 and BGBlitz at 5-ply
is around 0.6 and Mochy is about 2.3.
Or you may remember the Othello 2023 Quiz posted
a few days ago? What you call "garbage" solves
- 8 out of 10 with 1-ply
- 9 out of 10 wth 2-ply
- 10 out of 10 with 5ply (the 1st position is really a beauty)
