At the moment, Pebbles is creating a huge drift. Brian - CGOS requires us to use new names on the server each time we change our bots. It computes the strength using all games (heavilly biased with the results of the first 100 games)

Pebbles is probably closer to 2000 ELO than 1000 ELO based on the games against my bots. I did spot a bug in hb797-50k in its first resignation to Pebbles. My count was hb797-50k +1.5

Is there a rating drift? I remember that pure UCT no RAVE with 100k
playouts got over 1700 elo.
I will try to run it today again.

I've started two bots: hb797-10k and hb797-50k
They are pure UCT+RAVE with light playouts, one search thread, and no
pondering.
The number at the end represents the playouts per move.

I forget the approximate ratings for each version. I'll guess 1200-1300 for
10k and 1500-1600 for 50k.
I messed up the first round and both bots lost on time due to no internet
connection.

I can run my bot (1600-1700 ELO), but I may a few days depending on free
time over the weekend.

There are actually very few programs playing on CGOS (9x9). My engine is
rated around 1000, which means that it plays 75% of its games against
AverageLib (rating 670), and occasional games against Aya (rating 2300). All games have the predictable result, so I haven't been learning much lately.

I saw on Sensei's Library page http://senseis.xmp.net/?CGOSBasicUCTBots that there are a range of basic UCT implementations that would be excellent opponents (rating 1171 through 1603), but I haven't seen these players in
weeks. Is it possible to get them back up?

If so, I would deeply appreciate it.

Thanks,
Brian
