Sylvain, in the download notes, you mention that Mogo has some troubles with
"very long" timescales, due to the low resolution of single floats. Do you have
any estimate of how many simulations would lead to this situation?

but not linearly and you can see a nice gradual curve in the plot.
Now we have something we can argue about for weeks. Why is it not
mostly linear? Could it be the memory issue I just mentioned?
Hi Don and all participants to that study, that is very interesting!
The memory constrains are certainly a valid hypothesis, especially the default
settings of the release are rather conservative on that side, because it seemed
better to have a weaker player than begin to make the player's machine
swapping... Those settings are rather fitting your memory constrains as well,
so it is fine.
Reading your email and looking at the curve, I wonder if one possible
explanation could be an artifact on how the ratings are computed? My question
is: what curve would we see for that study if the involved players were exactly
linearly scalable? That seems silly, but I wondered if there were an
underestimating of higher levels, because of the way the bayeselo works. I am
also looking at the curve after the 5-6th level (~gnugo), as behavior may be
different for very low levels.
I don't know if my hypothesis makes sense.
Sylvain
