I checked it out. It seems only to switch between engines more or less at random.

Re: multi-pv tournament?

It's true that a supervisor program of some kind would have to make moves on a certain schedule (10s per move for example). Hardly impossible.

Re: eval blending?

Bad idea. Multi-pv is not free and costs valuable time. You're also assuming that a large gap means something. You don't know that. Perhaps the engine with the smallest gap sees something that the others don't? I'm not assuming anything, other than that it's an interesting idea which is worth trying.

eval blending?

Pardon if this has been discussed before, but has anyone tried blending evals of different engines to create an all-computer centaur? Blending is a popular technique in machine learning contests (it won the Netflix prize). We know something about the scaling of engines when adding cores. At what poi...

multi-pv tournament?

Has a tournament ever been tried with multi-pv enabled (say, = 3)?

Many humans use engines for analysis with multi-pv on, but how do we know strongest engine in conventional matches is still strongest when running multi-pv?

OK sure. But that is hardly justification for a rating system that ignores drawn games.

Re: Wilo rating properties from FGRL rating lists

LOS and p-value are independent of Draws I don't know where you're getting that but it's clearly not correct in this context. Consider an even simpler example than Larry's, and let's be sure to keep the number of games constant: A scores 100 wins against C; B scores 50 wins and 50 draws against C. ...
