Thanks Don, makes sense. Very impressive that you recalc based on the
results of ALL games! I think it is good to have two separate rating
systems for another reason - some engines learn. Bayeselo will give the
overall score across all games, but the rating system will potentially
give a better indication of the current strength.
Thanks again.

I have a question here. What is the rating on the main list,
and how does it relate to Bayeselo? E.g. if I look on
http://cgos.boardspace.net/9x9/bayes.html, I see that
_Gnu3.8L1_2 has an Elo of 1857 after playing 258 games. On
http://cgos.boardspace.net/9x9/standings.html (the only page
I normally look at for ratings) it has a rating of 1760
(after playing 258 games). How do these two numbers relate,
and also how will it work, copying the Elo across to the main
table, which at the moment doesn't look like it contains Elo?
Sorry to ask basic questions - I'm still new =)I see on the
Elo page that the Lazy,* bots have between them accrued 144
games. and have a combined Elo of 2111. But on the main
ratings page I see two separate bots, Lazy,0 and Lazy,1. Is
the idea that when you do the copy-over, the main ratings
page will also only show Lazy,* ?
No, the main page will always track the players as separate
individuals. So you should see Lazy,0 and Lazy,1 on the main page.
On the Bayeselo page, which has the most accurate ratings, you
will only see Lazy,*
When bayeselo runs it produces as output a set of sql commands
that (for now) I will manually run from time to time. They
just update the ratings field for the comma bots.
So as soon as I update the ratings of the comma bots you will see
them start drifting away until I do the update again.
I think any sync to baeselo should update all bots, not just the
comma bots. Without that, it may take a while for other stable
bots to resettle. It'll also make the comma bots drift faster if
you don't.
It's pointless to do that, we might as well just use bayeselo
exclusively. I actually considered making bayeselo the main page
and removing the other stuff.
But I think it would be annoying to get a certain rating and then
without playing any games come back a week later and the rating has
changed.
I think incremental ratings are best and what we are doing here is
making it a lot more stable.
It will take some time for the bots to re-sync, but that's ok. As
it turns out Bayeselo rating seem to be higher so no bot will be
rewarded for not playing. I think the rating pool in general has
been deflating so this will keep it stable.
