[postgis-devel] New node splitting algorithm for GiST

[Alexander Korotkov]

"A new double sorting-based node splitting algorithm for R-tree", A. Korotkov

I believe it's applicable to not very high dimensions (3 or 4). On 5 and
more dimensions guttmann quadratic algorithm could become more effective
than my.

With best regards,
