3.1.3DC vs 3.1.3

Which one is better Edit:found out that 3.1.3DC uses GoTo surfing

Both 3.13 and 3.13DC use GoTo surfing. 3.13DC uses DC, while 3.13 uses some form of VCS. (Correct me if I am wrong)

Correct :-) In the movement, to be more specific.

And considering I write a changelog, I don't see how this question is anything other than lazy at its worst.

I was always wondering why the best bot used VCS, DC seems much more elegant. Does it improve performance in your tests?

For some reason I've never managed to get the DC to perform as well as the VCS, so it still used VCS. I remember Jdev commenting that a range search worked better for him than a KNN search in movement, so I'll be trying that next.

Have you tried doing something similar to your many randomized attribute buffers with kD-Trees? You could make 100 trees, each with a random subset of the predictors, then combine the results. You could even start weighting some tree's results higher if they perform better.

In my mind, a tree is more heavyweight than a buffer. You need multiple buffers to begin to approximate the smoothing you get from KNN and kernel density. I use multiple trees in my surfing for the same reasons, but more on the order of 10 than 100.
