am now thinking maybe the minus sign should be interpreted literally. like maybe there is some invariant involving the number of red nodes minus the number of black nodes along some path or within some group of nodes. not sure what that invariant would be though
Interesting that this article title has a dash for left-leaning and a minus sign for red–black
I know there’s rules for when to use which. I’m not surprised that Wikipedia would care. I can’t keep them straight though.
