We haven't seen strong statistical evidence for intransitivity in computer go, but I don't think anyone has looked very hard yet. It seems like it probably exists to some degree - It would be interesting to study this. - Don [EMAIL PROTECTED] wrote: > I've mentioned this before, bu

I've mentioned this before, but hopefully not recently enough to make this annoying. Computer go people and corewars people overlap somewhat. Intransitivity is extremely important for corewars, making?corewars a good domain to study it. Here is an example of a nice graphical way to visualize in

you can use a multi-d ranking system to predict the outcome of a contest between two players. this is good for handicapping, for instance. this will not necessarily create a linear ordering of the players, as you've mentioned, but it is still quite useful, and radically more efficient and useful

Rémi, The idea of a non one dimension rating model is interesting. If you decide to pursue this I can give you the CGOS data in a compact format, 1 line per result. I thought of this idea too, but I didn't try to produce a model.It would be easier to test and build such a model however if

My guess is that this is a combination of some intransitivity and low sample size. 100 games isn't very much data in the CS vs MFGO. As far as intransivity, perhaps Crazy Stone has some particular strength that works very well against a weakness in MFGO. The values do not make a grea
